Why dont languages allow overloading of methods by return value?

Question

c, java and many other languages do not pay attention to return values.

int   i = func()
float f = func()
int   func() { return 5 }
float func() { return 1.3         


        

Answer 1

Let's say it was allowed, which one would this call:

func();

That may not the the full answer, but I believe that is one reason why it is not legal.
