That's fine for the VM and the support libraries, but I'd *really* like
to see the parser/front-end in Perl. There are dozens of RFCs that require
some non-trivial extensions to the parser. It would be nice to code these
in Perl -- especially if we can co-evolve the regex engine to support the
extensions. I think this would also help us document the interface between
the front-end and back-end (which could be a compiler or the VM). IMHO
this separation is worth it even if it costs us some performance.
