I tried to reduce as much as possible (maybe too much, we'll see...) an issue
which is blocking our work on std::bind. Note, the problem disappears if I
simplify the testcase further to not use variadic templates while keeping the
rest unchanged.
Jason, can you help us?

bool ready() { return true; }
void f()

bind(&State::ready, this);
