I have seen this coding practice extremely often and would be very unhappy if
it were not allowed any more. Imho automatic coercions are a good thing
and should be done where possible. Other extensible databases also allow this
without a cast. Imho the main culprit is finding a "number" format that will not
loose precision when implicitly propagated to.
