I agree with Chas and can support the AIX notion as I
work on AIX 5.3 machines which is the latest AIX.
But I did not see any response about:
Interesting though I ran perl -MO=Deparse on this
code...
So will foreach really be going away?
$ cat foo1
for my $i (0 .. 3) {
$i *= 3;
print $i,"\n";
}
print "\n\n";
for my $i (map { $_ * 3 } 0 .. 3) {
print "$i\n";
}
$ perl -MO=Deparse foo1
foreach my $i (0 .. 3) {
$i *= 3;
print $i, "\n";
}
print "\n\n";
foreach my $i (map {$_ * 3;} 0..3) {
print "$i\n";
}
foo1 syntax OK
