Implement Traversable/Foldable-Burning-Bridges Proposal
More details to follow. I've created this ticket to be able to refer to from related preparatory commits.
In a nutshell the FTP (Foldable/Traversable-Proposal) sub-goal of the BBP (Burning-Bridges-Proposal) includes to be able to compile code like the following w/o errors (due to conflicting definitions):
module XPrelude (module X) where
import Data.Foldable as X
import Data.Traversable as X
import Data.List as X
import Control.Monad as X
import Prelude as X
Other goals include to generalise/weaken type-signatures where possible w/o breaking (much) compatibility with existing code. An in-depth design-document is in the works.
