My strong inclination is to adopt this. The 'By' variants should
be consistent. That means changing GHC and Hugs a little, and correcting
the (a->a->a) typo in the current Report.
This seems to be the consensus of the messages so far, as well.
Yell if you object strenuously. Otherwise consider it done.
