I am curious whether either of you (Robert and David) have handled the need to evaluate the condition “is X (an object of type with some _potentially_ wide range) within bounds of Y (an object of type with some _potentially_ narrow range)?  I have use cases in which I would like use bounded types, but there are situations in which I need to capture the result of something like in_range<Y>(x).  I am not seeing this in your libraries but perhaps I am missing something.  It does seem quite feasible to include and would seem to incur no runtime cost under the same conditions that the construction Y y = {x} would not.

If I am missing this in your libraries, please let me know; otherwise, I throw this out as a suggested addition.

Cheers,
Brook
