[Haskell-beginners] Haskell.Exts parse failed: FlexibleContexts not enabled

[Daniel Lincke]

Hi,

when parsing a file containing a function signature with a context like
test :: (Functor f) => ...

I get the follewing failure:
ParseFailed "Malformed context: FlexibleContexts not enabled"

Actually I enables flexible contexts whereever I could ... any ideas?
