The following code does not compile ( error: no matching function for call to
`<unnamed>::A::print(main()::B&) ):
#include <iostream>
namespace {
struct A {
template<class C> void print(C c)
{
c.print();
}
};
}
int main()
{
A a;
struct B {
void print()
{
std::cout << "whee!";
}
};
B b;
a.print(b);
}
However, defining B in the same namespace as A, in a different namespace, or
even in the global namespace compiles and works as expected. I don't know the
standard well enough to say if this is correct behavior, but it seems like an
odd rule.
