"if (@foo) {...}" is *idiomatic* Perl for "are there any elements in
@foo, and if so, do this". If you don't understand the idioms, please
choose a more familiar language. :)
defined @bar and defined %bletch are almost never correct, and any
seasoned Perl hacker knows to watch for those as a red flag.
