Expected Example to validate that :attr looks like an integer greater
than 18 and less than 99, but this could not be proved.
In checking that Example disallows :attr from being a number that is
not less than 99, after setting :attr to "100", the matcher expected
the Example to be invalid and to produce the validation error "must be
less than 99" on :attr. The record was indeed invalid, but it produced
these validation errors instead:

As indicated in the message above, :attr seems to be changing certain
