[Haskell-cafe] Trouble with Haddock

First time using haddock. I'm unable to include code examples in the module header. Haddock fails with this error: haddock module header parse failed: Cannot parse header documentation paragraphs It's about 12 lines of code, which doesn't seem like much compared to other packages. e.g. -- | describing module -- -- > code -- > ... -- > code module Foo ( .... I tried @...@ code blocks, but that didn't work either. If I shorten the code to 3 lines or so, it will work.
