This is a feature used in real > code. Presumably explicit instantiation would still be permitted. Eg calls like: double x = func( 1, 2 ); would compile with the same semantics as now. Only types not specified explicitly and not deduced from arguments would be deduced from their initialising expression. It would be a last resort. I have to say, the phrase "last resort" is very disconcerting when used in conjunction with name look-up rules.
