I agree.

The question is whether we mind lots of people reimplementing this 
themselves, each using their own different name for it. I believe I read 
about some plan to add a trivial function named "on" to one of the 
standard libraries, because having it there makes code more readable. So 
the question becomes "does putting this thing in the library make 
people's code clearer, or is the function trivial enough to reimplement 
that one can readily see what it's for?"

I'd prefer it in the library (probably Data.List), but it's no biggie.
