I'd have thought that in the case: // id anonymous float f = [anonymous position]; the compiler ought to assume that the method being used is the one returning a float, or if not at least warn about an implicit cast from CGPoint to float. Perhaps if it were -(int)position rather than -(CGPoint)position, you might not expect a warning, but in that case you would expect a cast, so it shouldn't break. However, that does appear to be what is happening. In the absence of any other explanation, I'd call it a compiler bug.
