Performs filename expansion (globbing) on expr , returning the next successive name on each call. If expr is omitted, $_ is glob bed instead. This is the internal function implementing the <*> operator, except that it may be easier to type this way.

The glob function is not related to the Perl notion of typeglobs, other than that they both use a * to represent multiple items.
