That's what I tried first, then realized that it won't work with a
static function. Reading your answer it eventually dawned on me that
you meant static class members, not static free functions. I'll remove
the static declaration and go the original route; this will add a new
external symbol but who cares.

Yes, but I think it isn't worth the trouble: people should simply use
the backported 2.3 instead for anything serious.

Fair enough. If you prefer to do the tests yourself, that's also fine
with me, just describe the required setup. Otherwise I'll come back at
you when the fixed packages are built.
