my $counter = 0;
foreach my $e ( a .. z ) {
$counter++;
if ( $counter == 5 ) {
}
}
I know this is a perl idiom but I, and I suspect others, would find a perl
variable useful for the keeping the count when iterating. The draw back
with the above is that $counter
You probably can use 'state' instead of 'my' to keep $counter in scope.
foreach my $e ( 'a'..'z' ) {
state $counter++;
if ( $counter == 5 ) {
say $e;
}
}

and what if that code is run again in the same program? it will keep the
That is true.. Perhaps it's better to introduce a bare block enclosing the
loop, and declare $count as 'my' just before 'foreach'.
