Any vs All #28

Closed blargg closed 8 years ago

blargg commented 8 years ago

Based on the names, it seemed like the semi lattice instances for Any and All should be opposites (roughly, Any = Op . All). It looks like Any and All have the same instances right now. Would it be better to make Any and All opposites?

The instances are the same as for Bool. In the context of All and Any think \/ as || and /\ as &&.

Sounds good to me.
