Generally yes, but I'd define a new data IfaceLamBndr, rather like IfaceLetBndr, rather than clutter up IfaceLam itself.
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.
