When I remove the glasses, it smells more like making excuses. But as we saw discussed in the previous thread, I too think it is OK to make 'Nobody would notice the updated behaviour of NUL in the patterns' our working assumption and see if anybody screams---after all we have to start somewhere to make progress. A very good thing about this series is that it does *not* add a new feature that people would miss, even if it went straight to 'master' and to the next release. All it does is to optimize differently and changing the behaviour we assume nobody depends on. It is easy enough to revert the whole thing if it turns out to be problematic even in the worst case, and nobody would notice ;-)
