Minimal example program:
#include <iostream>
#include <algorithm>
template< typename T > struct A;
template< typename T, typename U > struct A< std::pair< T, U > >
{
static void f()
{
std::cout << __PRETTY_FUNCTION__ << std::endl;
}
};
int main()
{
A< std::pair< int, int > >::f();
}
Output of __PRETTY_FUNCTION__ from this program:
static void A<std::pair<_T1, _T2> >::f() [with T = int, U = int]
Problem:
_T1 and _T2 are printed as the pair's parameter names, but it then say T=int
and U=int.
Additional information:
This only seems to occur with partial specialization.
