This one I don't understand. I don't understand why converting the first char to lower case is bad here or how it relates to your example.
Me neither. The problem is that, if the original is FunctionFoo and the renamed functionFoo, the original code thinks that they're the same and replaces functionFoo with Nothing, which then amounts to outputing {#fun FunctionFoo {...#} instead of {#fun FunctionFoo as functionFoo {...#} , which of course chokes ghc. -- (c) this sig last receiving data processing entity.
