Spencer could better articulate it, obviously, but the idea is that the
config will look something like this:

main = xmonad $ defaultConfig
              <+> extend keys [((_,_), _)...]
              <+> set modMask mod4Mask
              <+> ...

Here, 'keys' and 'modMask' aren't the record getters, but are Functional
References [1] that wrap the getter/setter (since there is no succinct
syntax to pass a record field setter). <+> is sugar for `mappend`, hence
the Monoid bit (I may have the above snippet wrong). I'm not sure where
the Endo bit comes in.
