Well it's certainly not going to be that, since the glob

Would it be possible to just add a named argument, without repeating any
part of the existing signature? Like:
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 quickly change the
behaviour of programs: IIRC tcl's syntax was inspired by them. But OTOH it
is too

Any specific reason for the minus there? Perl's not a shell (yet).
rename.SWITCHES{-v} = sub {
my ($o, $n) = @_;
print renaming `$o' to `$n'\n;
}
I think just using named arguments would be better

It's already being done:
rename $orig, $new :verbose;
sub rename($orig, $new, +$verbose) {
say Renaming `$orig' to `$new' if $verbose;
...

Because one may want to restrict the number of pairs to be interpreted as
cmd line switches, I'm not even sure
