Re: [Haskell-cafe] Monad transformer responsibilities

Hi, it's alomost the same problem when you're writing a library with optional quickcheck test cases: Where to put the Arbitrary instances? - You can't put them into quickcheck - You don't want to put them in the library (because of the quickcheck dependency) - So you have to declare them near the test cases and they're orphan instances The entire project doesn't issue a single warning when compiling with -Wall *except* two orphan instances when building the test cases... //Stephan -- Früher hieß es ja: Ich denke, also bin ich.
