While I understand that this may seem appealing, it really isn't. Labels 
are in a different namespace IIRC, and using that for psuedo method 
calls is really an abuse.

I accept that my proposal doesn't allow custom iterators, but I don't 
believe that to be a major problem. Consider it that my proposal tackles 
80%+ of the problem (which was part of the 20% of the original looping 
problem, and still a good number of LOC in a reasonable system).
