These were 'probably' safe anyway, since they mostly treat the objects
as integers without checking, which at least can't result in a crash.

Nevertheless, we ought to check.

The return from comparedictkeys could be wrong if one of the keys had
a value which was not an array, it could incorrectly decide the two
were in fact the same.'
