heh, that’s what I ended up doing :-)

It seems to work quite well, I’m heating my room right now with a few
nofib runs of various combinations.

Also your suggestion to investigate fft2 was good: Turns out iterateFB
would never inline, which defeats the purpose. With that fixed (just
pushed to master) I expect Call Arity to handle the case in fft2 as
well; well’ll see when the benchmarks finish.

Greetings,
Joachim
