Recently on Haskell-Cafe, the topic of imports came up. I noticed this page does not detail the ability to import the same module multiple times under different conditions. Here's an example:
> module Main where > > import qualified Prelude as P > import Prelude ((++),show,($)) > > main = P.putStrLn (show $ P.length $  ++ [2,3])
I'm not sure if this is exclusive to GHC, or whether it's H98. If it's the latter, then it should probably be on this page. If it's the former, it may still be good to have here.
