No. You have effectively hidden the previous value of $_ in the inner loop,
and there is no way currently of getting to it again.
By alias I assume you mean a named iterator, i.e.:
foreach my $foo (0 .. 4) {
...
}
where $foo is what you're calling an alias. You'll have to use a named
iterator for one of the loops.
Out of curiousity, why do you prefer not to use a named iterator? They're
often more readable than the ever-implicit $_, especially if you end up
referring to the variable explicitly in the block.
