This is parsed as MyClass::operator+ (whitespace is not significant),
so you end up missing the return type.

Then the friend declaration injects the name in the enclosing
namespace ns, so that's where you'd have to define it. A definition
in the global namespace doesn't match, so it isn't granted access to
private members.

Adding parentheses around the declarator id (::operator+) should work.
