Re: Return type hints

Hi!

Let me turn your question around: Why on earth would someone restrict a function to int when string works just as well? function int foo_flexible(scalar $x) { return $x + 42; } $foo = foo_flexible($value);

Now let's think - what happens if $x is *not* scalar? So the real code would be like this: function foo_flexible(scalar $x) { return $x + 42; } if(!is_scalar($value)) { $foo = foo_flexible($value); } else { // ok, what do I do now? } And so for each instance. Ugly.

That said, I'll be using function foo($x) { return $x + 42; } anyway and let PHP warnings take care of the rest ;-)
