I'm not sure this is a bug or just my ignorance of the rules.
#include <iostream>
struct R{};
struct S{};
struct T{
operator R() {return e;}
operator S() {return f;}
R e;
S f;
};
void Bar(R r) { std::cerr << "Bar\n"; }
void Foo(S s) { std::cerr << "Foo direct\n";}
template<typename U>
void Foo(U u) { std::cerr << "Foo template\n"; }
int main() {
T t;
S s;
Bar(t);
Foo(s);
Foo(t);
}
gets you:
~/ootbc/common/test/src$ a.out
Bar
Foo direct
Foo template
That is, it takes exact match over universal template, and universal template over user-defined conversion. Is this right>
