the changes from 1.5.1 to 1.6.1. At first blush, it looks like there are
a lot of changes to swallow that are not necessarily minor. I really
would like to just say all is well, and it's no big deal. I hope that
users really don't care and nobody's code is really relying on array-scalar

solidifying the casting rules? We would need to add cases for overflow
that are currently handled differently than originally specified.
I don't think it is so much a question about whether or not to solidify
these casting rules as much it is about being aware of changes in the
table. This prevents accidental changes and forces us to make purposeful
changes to the agreed test results.
This would also make it very easy to diagnose cross-platform differences.
Of course, the question is, what do we consider to be the "truth" data?
