I noticed yesterday in my config, 'import qualified XMonad.StackSet as W', and I wondered - why do we do that? Is there some rationale behind it or is it just tradition?
I ask because if the former, then there are quite a few modules in XMC which don't import it as W, or as anything at all; a quick grep:

If the former, then several of these need to be fixed or changed, I think.

It's qualified because some names are reused: XMonad.StackSet.focus, XMonad.Operations.focus Consistent qualifications make it a bit easier to understand code, but you can usually tell between those: if you imported both modules as different random names, the types are sufficiently different that you can guess which is which (Window -> X ()) is used quite differently than (Stack a -> a). I'm not against widespread changes to import style in the name of consistency, but do take care to address unapplied patches beforehand, to avoid having to resolve conflicts. -- Adam
