I think MarLinn was highlighting that this line:
foo ‹（’-’‹） bar = False
Should read like this:
foo ‹（’-’）‹ bar = False

Brackets.
Yes, brackets, but why is this a problem?
I found this code [1] in GHC which seems like it might be relevant. Is it? It seems to suggest that classes Pc, Pd, Po, Sm, Sc, Sk and So are allowed in infix names, but Ps, Pe, Pi and Pf are not. Am I reading that right?
