We could do like the core does with [bind] or [wm protocol] and make it so that the empty string goes to NULL but any non-empty string that is still equivalent to the empty list goes to the empty list (I think there are better examples too, but I can't think of them right now). Slightly tricky, but valid. Donal. |
