///TODO: This is a WIP that is meant to replace the pattern of having two
///TODO: for_each() overloads in every interface where one takes a closure
///TODO: which returns a bool, and the other takes a void closure. In the
///TODO: majority case, the void overload simply calls the bool overload and
// TODO: returns true. In the minority case, the overloads are optimized. This
///TODO: device should be useful in the majority case.
