Just kidding, actually I worship
$_, but today, I seek wisdom for a conondrum which rattles my faith in this most holy, virtuous, and altogether nifty variable. If
$_ is a global variable, how does
$_ become
quasi-lexically scoped:
my @l = (1,2,3,4);
my @m = qw(a b c d e f g h);
for (@l) {
for (@m) { print " $_ " }
print " : $_\n";
}
outputs
a b c d e f g h : 1
a b c d e f g h : 2
a b c d e f g h : 3
a b c d e f g h : 4
How does
$_ get its value reset from the last
'h' value of the inner loop back to the numeric values of the outer loop? I was under the impression that
$_ (namely,
$::_) was a global variable. So what's story? Thanks for enlightening me...
