I happen to reach this topic in Lippman's book in the last few days.
Seems to say different thing to what ARM is quoted to be saying above.
I don't have the book with me right now. But essentially, Lippman says,
"When there is no exact match, standard conversion is applied to resolve
the overloading and NO PREFERANCE IS GIVEN TO ANY TYPE OF CONVERSION."
In such case, the given example should indeed produce ambiguous
overload error ( ?? I'm still not used to proper C++ terms yet  :-) ).

So, is Lippman wrong ?
