The location here should probably be empty rather than `#f' no? It looks
as though the value is coming from the internal %location, rather than
the user-provided location. If the two fields can shadow each other,
then indeed, that looks like an existing bug that was exposed by the
reordering, rather than a bug with the reorder itself.
I'll if I can find anything the macro, it looks quite complex to me :-).
