Given that the design could well be applied to other slots as
well, I think you've got a point there. The idea behind the
flag was to signal that slots will no longer make object type
assumptions which they could previously. Right now, only numeric
types support this feature. In the future I could imaging
strings and other types involving coercion would also want
to use the feature.

Given this design idea, how about calling the flag
