built for the Rakudo Perl 6 compiler and the NQP Compiler Toolchain.  Highlights
include:

@itemize
@item Great Unicode support, with strings represented at grapheme level
@item Dynamic analysis of running code to identify hot functions and loops, and
perform a range of optimizations, including type specialization and inlining
@item Support for threads, a range of concurrency control constructs, and
asynchronous sockets, timers, processes, and more
@item Generational, parallel, garbage collection
@item Support for numerous language features, including first class functions,
exceptions, continuations, runtime loading of code, big integers and interfacing
with native libraries.

machines like MoarVM, the JVM, and others.
