It's not possible in the general case.

http://stackoverflow.com/questions/13151072/

It might still be an attractive feature to have for specific, common cases, but
it would either have to be defined as a "compiler's best effort" thing, which
hurts portability, or defined to only work for a select few specific cases.

The latter is what's currently done for IFTI, but the rules are intuitive,
especially thanks to eponymous templates.
