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.
