But each invocation of operator <<() must be evaluated, if only
to learn that the ostream is disabled, right?  That could amount
to a lot of overhead or clients would need to write custom
functions that return a string from a set of arguments to reduce
the number of operator <<() invocations.

Otherwise, it sounds useful.
