Unlike the rest of the comments so far, I am
+1
to this proposal.
It has the only reasonable semantics.
There are at least two reasonable choices. The first is this. The second is given by the fact that for any Num a and Applicative f, we can write Num (f a) by lifting all the operations. I suppose the one proposed here might be more commonly used. -- Dan
