That's right, but there is a case where "function" really differs from 
"procedure". I mean protected objects. "function" vs. "procedure" for a 
protected object could potentially mean different implementation and 
performance. So I think that one should leave "function"s as they are, and 
just allow procedures with results:

   procedure Foo (...) return Bar;
