I'm not real sure why it's moaning about the "<" check but not the
">= 0" check, which ought to be equally tautological given the
assumption that the input is a valid member of the enum.  But
in any case, exactly how much value do these assertions carry?
If you're intent on keeping them, perhaps casting child_type to
int here would suppress the warnings.  But personally I think
I'd lose the Asserts.

Yeah, it's not a very valuable assertion. Removed, thanks!
