Im new to Erlang - so its just that - a guess. But ... when I imagine 
what the machinery for a message send is, compared to what I know the 
machinery for a function call is, at last in broad strokes, if a fun 
call isnt faster, it should be.

The speed is one thing - but I think the more important reason is that 
the fun call subsumes the message receive, that is, the 
generator-as-repeated-fun call can implement receive functionality 
easily if desired, but it would tend to be awkward to do it the other 
way around.
