When trying to initialize fu2::function_view<float(float)> with an object of type fu2::function<float(float) const>, clang 14 spews out an incomprehensible error message without a proper "instantiation stack". It is possible to infer what the problem is from const T not being castable to void* inside address_taker, but I think a proper concept or static assert based error message would be much preferred.
