my @globlist = glob '*.{txt,aux}';

That is a shell glob expression, but we're assured it's portable.

Actually, that's a csh or ksh glob expression, not a shell glob expression. And since Perl would actually run on machines that didn't have csh (gasp!), it's not completely portable in the same sense as Perl.

However, the difference would probably be nil for most modern Perl users.
