#coerce only seems to work for Numerics (unless that has changed in
1.8?), and as you note, isn't called for ==.
Actually, I think an extension of the coerce mechanism might be
cleaner than my proposal, and could avoid the potential problem (noted
in another post) of having to do 2 comparisons for each == operator.

I will think about it and post another proposal based on #coerce later
today.
