[xmonad] How to organize myLayoutHook?

[Jeffrey David Johnson]

Thanks, that's good to know I'm doing things generally right. Maybe a 
more specific question would help me improve it though... what I'm 
actually trying to do is make a tabular list of workspace properties 
like this:

myLayoutHook = avoidStruts $ smartBorders $ format
     [ ("admin", "~/dotfiles", (Full, tall, Grid, wide))
     , ("notes" , "~/notes"  , (tall, wide)               )
     ]
     where
         tall    = ...
         wide = ...
         format = ???

And I can't figure out what the format function should be.
