I would love to get more information, but I'd be very happy with the diagnostic above (that's already better than I'd get from any compiler I've tried) This PR is really just to get *anything* printed, so just a basic "substition failed" with no mention of which template parameter failed would be enough to resolve this IMHO. Improving on that would be a nice-to-have, for a later date.
