> Fixing the space leak is important to me. If the performance is an
issue, then perhaps it should be an `-O2`-only optimisation?
Perhaps. It seems to cost about 9% of the compile time of a -O build, so
it's not a /massive/ problem.
Anyway, I looked a bit more at this arity stuff tonight and I've managed
to fix a few bugs in the analysis, as well as make it work across several
modules - this makes it /slightly/ more effective, and has fixed the
problems I mentioned above.
I'm going to continue tuning and extending it, and will talk to Simon PJ
when I have something potentially viable for HEAD.
