--------------------------------+-------------------------------------------
GHC gets stuck in the simplifier when compiling the attached file,
eventually exhausting all ram.
Compiling gives:
{{{

*** Simplifier:

}}}
Running with with all the dump flags suggests the fault is pddlDocExpr's.
I'm finding it hard to create a smaller example, as even silly things like
removing the container (or not using Data.Generics) restore termination.
