['FOO'] or ['foo']? Both answers are justifiable. Both are possibly even useful depending on context...
I think it would be best to leave it as an implementation detail, because whichever is easiest to implement depends on the exact implementation choices (e.g. C vs. Python).
I think this is the point where the datatype is *not* clearly straight-forward, and thus deserves a PEP.
I think it would be a flaw to have this detail implementation-defined. This would be like saying that it is implementation-defined which of A,B,C is returned from "A and B and C" if all are true.
