Yeah; all existing operators have their meaning, and might apply to
some or all alternatives one might use. C++ doesn't allow defining
new operators (probably for good reasons), and I'm generally wary of
overloading operators for unrelated purposes (don't already like the
stream "<<" and ">>" too much).

Well, with "using std::move" it's a bit shorter (just "move ($n)"),
but still too much clutter for my taste.
