# Potentially a compiler bug:
# - A proc() without the Loop parameter doesn't crash the compiler
# - a proc(l: Loop) will cause a consistent compiler crash ==> SIGSEGV: Illegal storage access. (Attempt to read from nil?)
# Compiler is "Nim Compiler Version 0.10.1 (2014-11-10) [Linux: amd64]" from master branch
