Hi all,
This is my change to make (Stack a) never be empty, with possibly empty stacks represented by (Maybe Stack a). This slightly simplifies the layout code, since we handle the case of no windows in the core. This assumes that we don't have a layout that needs to do something with an empty screen.
This looks ok. Some code gets easier, some gets harder, but we do get a type for non-empty workspaces. So that's good.
Anyhow, one step in my campaign for powerful, safe extensibility. The main thing we need to do, though, is to catch exceptions...
Great! -- Don
