in std namespace?

Yes. You are allowed to _specialise_ any of 'std' templates for your
particular types.

So, the first of the following two functions is OK, but not the second,
since the second is an overload and not a specialization?

class MyClass;

namespace std {
template<>
void swap<MyClass>(MyClass&, MyClass&);
}

namespace std {
void swap(MyClass&, MyClass&);
}
