virtual machine for Rakudo Perl 6 and NQP

 Short for "Metamodel On A Runtime", MoarVM is a modern virtual machine
 built for the Rakudo Raku (formerly Perl 6) compiler and the NQP Compiler
 Toolchain. MoarVM is used by the majority of Raku programmers.
 .
 Highlights include:
  * Great Unicode support, with strings represented at grapheme level
  * Dynamic analysis of running code to identify hot functions and loops,
    and perform a range of optimizations, including type specialization
    and inlining
  * Support for threads, a range of concurrency control constructs,
    and asynchronous sockets, timers, processes, and more
  * Generational, parallel, garbage collection
  * Support for numerous language features, including first class
    functions, exceptions, continuations, runtime loading of code,
    big integers and interfacing with native libraries
