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.
