Generalizing bind itself would rather be a topic for ICFP or POPL, and I 
cannot comment on that :-) Concerning the constant that represents it 
syntactically, I would say that if it does not break anything then it is 
fine. After all, this is just ad-hoc overloading, so generalizations can 
also be ad-hoc.

Pushed to testboard, which should run it on decent hardware:
