I'd like to be able to define functions for every possible label,
including labels that might get added later, rather than for a single
label. Extending the existing label class would be the right way to do
this. Of course there are other ways (I'm using them now), I was just
hoping for something cleaner.
Well, if there's no way to extend element classes or basicElement
itself, perhaps Google can consider this a feature request?
