Try this under the current for system, cause it's unclear what will happen
for those new to Perl:
$foo=monkey; $_= coward;
for($foo){
Why would you want it to print Monkey Hero, I would expect $_ to be
localized, rather than global, which could prove more convenient.

That's bizarre and unnecessary. We can already do this:
for ( \@foo, \@bar ) {
print $_-[0] :

No, it's still localized.
But the With would mean that $_ in a way becomes a normal variable like $foo
was, and the $foo is now the 'default variable'.

Both the following would work:
with($foo){
print I am not a $foo\n;
# or:
print I am not a ;
print;

Okay... I've been mostly ignoring this thread. But can someone reiterate the

I question this too, since as you mentioned with, in my experience works
nicely to reference and object like
with(object)
{
.foo();
.bar();
}

I believe what is really wanted is for for to be able to iterate
over lists of arrays or hashes:
for my @i ( @foo, @bar ) { ...
for my %i ( %foo, %bar ) { ...
with real aliasing occuring.
If @_ and %_ are the default iterator variables, then imagine:
for ( @argset1,

coward which can be easily done with print I am not a $_; will now have
to be written in two separate lines, and possibly more if there is more to
follow.

Um, of course the original way is still possible!
