that group was removed over a decade ago. your news feed shouldn't even
have it. the group you want is comp.lang.perl.misc.

don't use quotes for the first arg to split. it is always a regex so use
// like other regexes.

just slice it. no need for the anon array:
(split m{\\.}, @ARGV[0])[0];
i used m{} for the regex since // would look badly with \\ inside.
