I seem to remember someone proposing something similar for std::unary_function
;-) The argument seems even weaker here: base_from_member is designed for
private inheritance, so it's hard to see how it can be misused by clients of a
derived class.

There's one change I'd like to see: the constructors should take rvalue
references ;-)
