Initially I suspected the culprit was the monomorphism restriction being
turned off by default (:showi language in GHCi, (great thanks to Brandon
Allbery who mentioned this command on another thread)), but I don't
really see a difference when I turn it off.

Oh, I see.

That's kind of funny.  Seems somewhat inconsistent to my eye.
