You just did in fact. Your idea with defining some internal types is very
similar to one of the promising solutions we've been exploring for resolving
signedness of arithmetic operations.

I will in fact stop here and paste the rest of my message to the main newsgroup
because it's of general interest and segues away from this bug report.
