Yes.
Isn't the underlying issue in the above how perl6 handles manipulation
and aliasing of multi-dimensional arrays i

No, it's still localized.
But the With would mean that $_ in a way becomes a normal variable like $foo
was, and the $foo is now the 'default variable'.
@foo = ("foo1", "foo2");
@bar = ("bar1", "bar2");
for ( \@foo, \@bar ) {
print "$_->[0] : $_->[1]\n";
}
will output
foo1 : foo2
bar1 : bar2
I was thinking more of iterating through them at the same time, which would
sort of like compare them. I believe this was the initial topic of

That's bizarre and unnecessary. We can already do this:
for ( \@foo, \@bar ) {
print "$_
Why would you want it to print Monkey Hero, I would expect $_ to be
localized, rather than global, which could prove more convenient.

Try this under the current for system, cause it's unclear what will happen
for those new to Perl:
$foo="monkey"; $_=" coward";
Agree. I think that with() should only be used with object references only,
and $_ should be set accordingly.

Well then maybe $_ can be a reference to a multidimensional array or hash,
and temp vars can be access like this.
for ( @foo, @bar ) {
print "$_->[0] : $_->[1]\n";
}
As for hashes it might hold the key, also in an multidimensional array.

Um, of course the original way is still possible!
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,
I question this too, since as you mentioned with, in my experience works
nicely to reference and object like
with(object)
{
.foo();
.bar();
}

Well if you look at the proposed...
$_ = "monkey ";
$foo = "coward";
with ($foo){
print;
print "$_";
}
Would print "coward monkey", which will give you unexpected results if you
are used to having the same output for both, "coward coward".
But I guess the above would not replace
