cmd line like switches for functions and operators.

I know that it is probably (a few years) too late for a proposal like this, that is highly "invasive" wrt Perl's semantic, but here it is anyway... Cmd line switches are so useful and effective to ...

if, loop, and lexical scope

AFAIR, I've seen in some Apocalypse that lexical scope boundaries will be the same as boundaries of block, in which lexical variable was defined. so, my question is, what the scope of variables, ...

A stack for Perl?

This is yet another proposal that is probably a few years late. I've had some (admittedly limited) experience with S-Lang in the past: the language has currently a syntax that resembles much that of ...

more than one modifier
