I want to see Perl become a full-blown C/C++ JIT.  Since Perl is for
a large part a compatible subset of C I don't see this as unrealistic.

Delaying any post-token parsing of barewords until after looking at
what local declarations are in effect is part of it,  dealing with the
one or two differences in operator precedence that exist is another

(Old precedence semantics unless  new-ism like a declared typed bareword
exists in the current or a surrounding block would be the easiest way to do
it I think)

Typed barewords as an available good syntax would please those who find
perl overpunctuated.

XS would become a more proper part of the language, the line would blur
as we could mix Perl and C freely with very little performance loss due
to late binding except in things that are not known at "compile time"
things which by definition cannot be clarified without run-time inputs.
