FWIW, I strongly support option #1 above.

I think it's about time that "features" that make Erlang weird get 
eliminated from the implementation.  It took me several years to 
convince the OTP team that they should eliminate tuple-funs from the 
implementation.  They finally did and, unsurprisingly, the world has not 
stopped turning, nor did anybody decide to stop using Erlang for what it 
is good at, simply because it had no "tuple-funs" any longer.  On the 
contrary, I think we have a slightly better language since their 
removal.  Similarly, I think it will become slightly better with the 
removal of "tuple dispatches".

Anyway, that's my .02.
