This is "Not Quite Perl" -- a compiler for quickly generating PIR routines from Perl6-like code. The key feature of nqp-rx is that it's designed to be a very small compiler (as compared with, say, perl6 or Rakudo) and is focused on being a high-level way to create transformers for Parrot (especially hll compilers). In addition, unlike Rakudo, nqp-rx attempts to restrict itself to generating code that can run in Parrot without the existence of any nqp-specific runtime libraries.
