in reply to Reverse the String
Reading the docs for reverse, one sees that it will reverse a string in scalar context (
$doog = reverse('good')results in $doog being set to 'doog'), but it will reverse the order of the elements of a list in list context (
@doog = reverse('good');results in @doog = ('good'), as a 1 element list looks the same when reversed (Perl may even optimize the reverse away in this case).
Since print expects a list (print ($a, $b, $c) is perfectly valid Perl), Perl's behavior for
print reverse('good');
is the same as it is for
@doog = reverse('good');

At that time [1909] the chief engineer was almost always the chief test pilot as well. That had the fortunate result of eliminating poor engineering early in aviation.
