		-- * intended to 'imitate' llex.c code; performance is not a concern
		-- * tokens are strings; code structure largely retained
		-- * deleted stuff (compared to llex.c) are noted, comments retained
		-- * nextc() returns the currently read character to simplify coding
		--   here; next() in llex.c does not return anything
		-- * compatibility code is marked with "--#" comments
		--
		-- Added:
		-- * luaX:chunkid (function luaO_chunkid from lobject.c)
		-- * luaX:str2d (function luaO_str2d from lobject.c)
		-- * luaX.LUA_QS used in luaX:lexerror (from luaconf.h)

		-- * luaX.MAX_INT used in luaX:inclinenumber (from llimits.h)

		-- To use the lexer:
		-- (1) luaX:init() to initialize the lexer
		-- (2) luaX:setinput() to set the input stream to lex
		-- (3) call luaX:next() or luaX:luaX:lookahead() to get tokens,

		--   in the interest of performance

		--   tonumber() function is already capable of this
		--
		-- Changed in 5.1.x:
		-- * TK_NAME token order moved down
		-- * string representation for TK_NAME, TK_NUMBER, TK_STRING changed
		-- * token struct renamed to lower case (LS -> ls)
		-- * LexState struct: removed nestlevel, added decpoint
		-- * error message functions have been greatly simplified
		-- * token2string renamed to luaX_tokens, exposed in llex.h
		-- * lexer now handles all kinds of newlines, including CRLF
		-- * shbang first line handling removed from luaX:setinput;
		--   it is now done in lauxlib.c (luaL_loadfile)
		-- * next(ls) macro renamed to nextc(ls) due to new luaX_next function
		-- * EXTRABUFF and MAXNOCHECK removed due to lexer changes
		-- * checkbuffer(ls, len) macro deleted
		-- * luaX:read_numeral now has 3 support functions: luaX:trydecpoint,
		--   luaX:buffreplace and (luaO_str2d from lobject.c) luaX:str2d
		-- * luaX:read_numeral is now more promiscuous in slurping characters;
		--   hexadecimal numbers was added, locale-aware decimal points too

		-- * luaX:llex: parts changed to support new-style long blocks

		-- * some unused C code that were not converted are kept as comments

		--
		-- Not implemented:
		-- * luaX_newstring not needed by this Lua implementation
		-- * luaG_checkcode() in assert is not currently implemented
		--
		-- Added:
		-- * some constants added from various header files
		-- * luaY.LUA_QS used in error_expected, check_match (from luaconf.h)

		-- * macro hasmultret is new
		-- * function checklimit moved to parser from lexer

		--   translates boolean back to 1/0 for instruction fields

		-- Notes:
		-- * WARNING! byte order (little endian) and data type sizes for header
		--   signature values hard-coded; see luaU:header
		-- * chunk writer generators are included, see below
		-- * one significant difference is that instructions are still in table
		--   form (with OP/A/B/C/Bx fields) and luaP:Instruction() is needed to
		--   convert them into 4-char strings
		--
		-- Not implemented:
		-- * DumpVar, DumpMem has been removed
		-- * DumpVector folded into folded into DumpDebug, DumpCode
		--
		-- Added:
		-- * for convenience, the following two functions have been added:
		--   luaU:make_setS: create a chunk writer that writes to a string
		--   luaU:make_setF: create a chunk writer that writes to a file
		--   (lua.h contains a typedef for lua_Writer/lua_Chunkwriter, and
		--    a Lua-based implementation exists, writer() in lstrlib.c)
		-- * luaU:ttype(o) (from lobject.h)
		-- * for converting number types to its binary equivalent:
		--   luaU:from_double(x): encode double value for writing
		--   luaU:from_int(x): encode integer value for writing
		--     (error checking is limited for these conversion functions)
		--     (double conversion does not support denormals or NaNs)
		--
		-- Changed in 5.1.x:
		-- * the dumper was mostly rewritten in Lua 5.1.x, so notes on the
		--   differences between 5.0.x and 5.1.x is limited
		-- * LUAC_VERSION bumped to 0x51, LUAC_FORMAT added
		-- * developer is expected to adjust LUAC_FORMAT in order to identify
		--   non-standard binary chunk formats
		-- * header signature code is smaller, has been simplified, and is
		--   tested as a single unit; its logic is shared with the undumper
		-- * no more endian conversion, invalid endianness mean rejection
		-- * opcode field sizes are no longer exposed in the header
		-- * code moved to front of a prototype, followed by constants
		-- * debug information moved to the end of the binary chunk, and the
		--   relevant functions folded into a single function
		-- * luaU:dump returns a writer status code
		-- * chunk writer now implements status code because dumper uses it
		-- * luaU:endianness removed

		-- * an Instruction is a table with OP, A, B, C, Bx elements; this

		--   to work with doubles and ints
		-- * WARNING luaP:Instruction outputs instructions encoded in little-
		--   endian form and field size and positions are hard-coded
		--
		-- Not implemented:
		-- *
		--
		-- Added:
		-- * luaP:CREATE_Inst(c): create an inst from a number (for OP_SETLIST)
		-- * luaP:Instruction(i): convert field elements to a 4-char string
		-- * luaP:DecodeInst(x): convert 4-char string into field elements
		--
		-- Changed in 5.1.x:
		-- * POS_OP added, instruction field positions changed
		-- * some symbol names may have changed, e.g. LUAI_BITSINT
		-- * new operators for RK indices: BITRK, ISK(x), INDEXK(r), RKASK(x)
		-- * OP_MOD, OP_LEN is new
		-- * OP_TEST is now OP_TESTSET, OP_TEST is new
		-- * OP_FORLOOP, OP_TFORLOOP adjusted, OP_FORPREP is new
		-- * OP_TFORPREP deleted

		  We assume that instructions are unsigned numbers.
		  All instructions have an opcode in the first 6 bits.
		  Instructions can have the following fields:
		        'A' : 8 bits
		        'B' : 9 bits
		        'C' : 9 bits
		        'Bx' : 18 bits ('B' and 'C' together)
		        'sBx' : signed Bx
		
		  A signed argument is represented in excess K; that is, the number
		  value is the unsigned value minus K. K is exactly the maximum value
		  for that argument (so that -max is represented by 0, and +max is
		  represented by 2*max), which is half the maximum for the corresponding
		  unsigned argument.
