RE: what's with 'with'? (was: [aliasing - was:[nice2haveit]])

[Sterin, Ilya]

@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 this
thread (I believe, that was about two days ago, my mind might be going blank
though).

So my initial code (which I modified a little...)

for ( @foo, @bar ) {
  print "$_[0] : $_[1]\n";
}

for would set each element of the @_ array to correspond to the arguments in
for() , therfore $_[0] will equal to the current element of @foo and $_[1]
will equal to the corresponding element of @bar.  As I mentioned before this
can very easily be accomplished through 0..$#foo loop, but people disagreed
based on that it would be a nice option, in my opinion it's useless, but if
was implemented this could be a way:)

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

  for ( \@foo, \@bar ) {
    print "$_->[0] : $_->[1]\n";
  }
