Agree. I think that with() should only be used with object references only,
and $_ should be set accordingly.

Try this under the current for system, cause it's unclear what will happen

But this only works for scalars. You can't have a %foo alias to

That's bizarre and unnecessary. We can already do this:

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'.

Yes.

Well in Perl5, for the print to use default

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,
