I'd say because overall, you gain *very* little out of it, and it 
costs you much more complex compiler rules.

Most of all though, I'd say it is a bad idea in and out of 
itself: If you overload on the return type, you open the 
floodgates to call ambiguity.

I mean, are there even any real use-cases for overload on return 
type?
