IMCC, as many people have pointed out, is a step in this chain, as it
means now that you can go:

   lexer->parser->simple code emitter->(parrot+imcc)

rather than

   lexer->parser->code emitter->optimizer->parrot

IMCC doesn't completely remove the need to translate to parrot
assembly, or something reasonably equivalent, but that's the next
step.

The plan, such as it is, is to get the perl 6 regex spec implemented,
and then use it to handle the front end parts, the lexing and
parsing. IMCC will be beefed up to take in ASTs that the lexer/parser
emit, and then it should just be a matter of building the rules.
