How about if we start a "Brain Teaser" section to PerlMonks? You could have "Newbie", "Intermediate" and "Perl Monk Master" sections. People could measure their skill level by seeing which brain teasers they are able to answer. It's also a great way for everyone to contribute through the offering of brain teasers. So here's my first brain teaser, at the "Newbie" level, of course.
What do you think the output of the following code is? Can you explain why? If you are stumped, click "Reply" to see the answer.
#!/usr/bin/perl -w use strict; my $aloha = "hello"; print reverse($aloha);
