What design problems are to be discussed? When we chatted about this on IRC
most of the discussion went onto how to make xmonad compile itself, which
really is a separate feature.
What remains to be fixed is the elimination of recursive imports from Main,
and that's pretty easy, just tedious: we just need to add those things to
XConf, and modify code to grab it from there.
The other thing remaining to be fixed is to make cabal build
xmonad-the-library, but that's just straightforward config hacking.
Oh, and we need to get rid of the existential Layout type, which requires a
non-easy-to-fix recursive import, but that's a problem that I believe is
solved except that noone pays attention. NewLayout doesn't require
existentials, and there's no reason why we shouldn't parametrize XState
with a layout type, which will eliminate the other user of Layout (not
counting SwitchTrans or Combo). Since SwitchTrans and Combo don't
currently serialize, we won't be losing anything.
