fix special-case recreation of *::
|
|
|
|
If *:: is called for then as a special case it is looked up as
|
|
$::{"main::"}. If $::{"main::"} has been deleted, then that hash entry
|
|
is recreated. But formerly it was only recreated as an undef scalar,
|
|
which broke things relying on glob lookup returning a glob. Now in
|
|
that special case the recreated hash entry is initialised as a glob,
|
|
and populated with the customary recursive reference to the main stash.
|
|
Fixes [perl #129869].
