Hello,

It seems that callback() template function isn't working with return types other than bool or void.
Is this intentional? Or is it possible to replace it with a more flexible one?

If so, maybe the below template function can do the job (IF I am not missing something here).
template<typename Res, typename... ArgTypes>
Function<Res(ArgTypes...)> callback(Res (*fn)(ArgTypes...))
{
	return [=](ArgTypes... args) { return (*fn)(args...); };
}
Best regards,
Oblivion

Callback is deprecated. Use Function.
