Element Interpreter in Perl

#Element is an interpreted programming language that I created in order to write very concise and human-readable programs for code golf competitions.
#Element follows the  principle of "One character, one function, all the time." This allows the language to be much easier to learn and understand (and to write an interpreter for).
#Element has three data structures: a main stack, a control stack, and a hash.
#One notable feature of Element is the ability to create variables using the hash.

#This interpreter is written in Perl because I felt that most of the commands were very straight-forward to convert into Perl, and because I didn't feel like figuring out how to write it in C.

#To use, run this on the command line as "perl interpreterfilename.plx".
#On the next few lines, you can type in your Element program.
#Once it encounters a completely blank line, it will convert the code to Perl and print it.
#It will then evaluate your program, taking input and printing output as needed.
