This will attempt to remove the entire typeglob associated with
C<$glob_name> from the package.
-=item B<list_all_package_symbols>
+=item B<list_all_package_symbols (?$type_filter)>
This will list all the glob names associated with the current package.
By inspecting the globs returned you can discern all the variables in
the package.
+By passing a C<$type_filter>, you can limit the list to only those
+which match the filter (either SCALAR, ARRAY, HASH or CODE).
