confuse by typeid()

[XHengDF]

#include "iostream"
struct C {
template <typename T> void foo(){}
};

int main()
{
std::cout << typeid( (&C::foo<int>) ).name() << std::endl;
}
output: int
anybody could tell me WHY?

thanks!

Doesn't compile at all for me. With gcc 3.4.4:

$ g++ -Wall -ansi -pedantic test.cpp
test.cpp: In function `int main()':
test.cpp:8: error: address of overloaded function with no contextual
type information

int main()
{
std::cout << typeid( (&C::foo<int>) ).name() << std::endl;

Which compiler? Looks broken to me.

Well I get 'void(*)()' from Sun CC, where I'd expect void(C::*)(). Must
be confused by the redundant template <typename T>.
