This is "Not Quite Perl" -- a lightweight Raku-like environment for virtual machines. The key feature of NQP is that it's designed to be a very small environment (as compared with, say, raku or Rakudo) and is focused on being a high-level way to create compilers and libraries for virtual machines like MoarVM, the JVM, and others.

Unlike a full-fledged implementation of Raku, NQP strives to have as small a runtime footprint as it can, while still providing a Raku object model and regular expression engine for the virtual machine.
