[Haskell-cafe] "Functional dependencies conflict between instance declarations"

[Peter Verswyvelen]

Never mind, that GHC compiler was again more clever than me, sigh.

That's really frustrating about Haskell: the compiler captures so many 
errors at compile time, that newbies hardly get anything done, it's a 
constant battle against the errors. But once it compiles, it usually 
works at runtime :-)

Happy hacking,
Peter
