After updating from ghc 7.6 to 7.10 it seems you can't :m [Module] or ghci> import [Module] where [Module.hs] is your hand-written module file that resides in current working directory.
It seems ghci searches only for modules that are part of haskell standard library and modules that are globally installed via cabal. (you can still :load [Module.hs] in ghci prompts though)
I think it's kinda annoying since you can't test whether my module definition is correct by directly importing them from ghci. Is there any switch or configuration that I can fiddle with, so I can tell where my haskell working dirctory is to ghci?
