Thanks Gevorg, that's what I needed. integer_sort is now safe against too-large data types, and the default float_sort is safe against bad casts. The warning message is confusing, but it's a compile-time warning, which is what I need to let the user know that there is a problem. Is it bad for my unit tests to be issuing intentional static warnings?
