Here is a yet simpler version of the problem
Thank you for the simplification! I guess we can also drop the type parameters of `Signal` and `Causal`. For now I have solved the problem in my package by adding type signatures to the let binding. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12526#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
