Type is fine for debugging, but in a final application I like to leave some
error checks - especially checks like this - in the code, so I can attempt
to gracefully recover.
In addition, the value not being in range isn't always an error. For an
obscure (and bad) example, I use this test to determine if a value is an
index (relatively small) or a handle (typically large). The code ran into
trouble when the handles became so large, the values were negative.

I don't see an overriding necessity, either. But I think that an inclusion
of something like this might help create safer code.
