Well, I don't know in detail how keyword arguments work from the C
side. Your suggestion turns a roughly 4 line change I knew exactly
how to do into a 20-30 line change I'd have to work on. I only said
"mildly painful". The awkwardness of use would just mean using **,
yes.

Well yes, but I think the latter is closer to what one means, which is
to say passing a (i.e. one) set of options.

Fair enough. I've probably been corrupted by C on this one.

At any rate, the fact that I'd temporarily forgotten about the
existence of Jython is the more serious blunder...
