[Voted into WP at April 2003 meeting.]
Proposed Resolution (4/02):
Change the last chunk of 13.10.3.4 [temp.deduct.conv] paragraph 2 from
If A is a cv-qualified type, the top level cv-qualifiers of A's type are ignored for type deduction. If A is a reference type, the type referred to by A is used for type deduction.to
If A is a cv-qualified type, the top level cv-qualifiers of A's type are ignored for type deduction. If A is a reference type, the type referred to by A is used for type deduction. If P is a reference type, the type referred to by P is used for type deduction.
Consider:
struct S {
template <class T> operator T& ();
};
int main ()
{
S s;
int i = static_cast<int&> (s);
}
13.10.3.4 [temp.deduct.conv] says that we strip the
reference from int&, but doesn't say
anything about T&. As a result, P (T&)
and A (int) have incompatible forms
and deduction fails.
