I’m not sure why you thought map would be easier than foreach.

Originally I didn't have a foreach, it was actually just a for (my $i = 32; $i < 127; ++$i).  That's why I said "... basically something like this ..."  I modified it later to have a similar "look" as the (almost) equivalent map construct.

And your point about "next" and "last" is both correct and ironic, because the first thing that happened when I switched to map was that I ran into the problem of next not being usable and having to be written differently, which reminded me of this recent question.
