-If C<$what> is a glob, it's equivalent to C<local *x;>, and C<$key> is ignored.
-If C<$what> is a string beginning with C<'@'> or C<'%'>, it's equivalent to respectiveley C<local $a[$key]; delete $a[$key];> or C<local $h{$key}; delete $h{$key};>.
-If C<$what> is a string beginning with C<'&'>, it's more or less of equivalent to C<undef &func;>, but actually more powerful as C<&func> won't even C<exists> anymore.
