I'd see something like that as useful within CM if it can replace this
kind of code
---
if (p < 0 || p > 1) {
throw new OutOfRangeException(p, 0, 1);
}

There are examples in "MathUtils" (e.g. "checkFinite").
I.e. it should come with an exception that inherits from
"OutOfRangeException" with a customized error message.

Did you spot places in CM where this could be used?

I think that attachements are stripped by the ML manager. :-/
