Partly it seems to be because of the Choose type in 'xmonad/XMonad/Layout.hs',
which is used in a recursive manner to combine the layouts (|||).
I think it's done this way to be able to combine different layout types,
which all have an instance of LayoutClass, without needing existential
By using existential quantification it might be possible to represent
the combined layouts by just a list, and the current layout could
be indicated by a lens.
Or I'm missing something regarding the Choose type?
