That's closer to the truth, though the RFCs that don't introduce brand new
concepts generally affect the runtime behaviour of perl rather than the
compile-time behaviour, though some do both.

Perl's biggest barrier to doing this is the difficulty of determining what
a token is, and that's really what stands in the way. Changing how the
parser deals with tokens is reasonably simple compared to that. (Well, as
simple as writing parser code) Lexer abuse is needed for things like
Python mode, though--without it that's a no go.

We may be able to fake it with source filters and parser abuse, though.
