How's this for a radical thought --- optional<T> should not be assignable from T. That way, it doesn't matter whether T is a reference, or not.
There's at least some precedent for types that are "immutable except for copy assignment."
The assignment from T is really a kind of mutating operation.
Indeed. I'm leaning fast into dropping assignment form T. That definitely solves the reference binding issues.
