I, personally, would want to be warned on any implicit down-conversion between
native types. In cases where "down" is ambiguous (ie. with non-native classes),
the warning should be specially requested, as it could be generally annoying. 
I would actually argue that xxx(int)/fxxx(double) is such a minefield that it
deserves special case warnings.
