All right, I've done my duty as the Loyal Opposition ;-), and I don't
care enough to keep arguing.

That still leaves the question for what *is* allowed within the
brackets.  AFAICT, the options are

* A single identifier (which must be a callable)

* Comma-separated list of identifiers (which must be callables)

* Arbitrary expression (which must produce a sequence of callables)

BTW, have we agreed on the order in which decorators will be applied?
