<pre>Yeah, I'm going to resolve this as invalid - seems GCC and Clang both accept
the code, and it boils down to something like this:
struct Bad { };
template <typename T>
struct is_Foo {
void (T::*hello)(int) = &T::hello;
constexpr static bool value=true;
};
int main() {
return is_Foo<Bad>::value;
}
- instantiating the class and the static member 'value', doesn't instantiate
the non-static members.</pre>
