@Razetime - 'I can also work as a higher order function' - Ok, now you've said that I can understand what Leo said, if that's correct.
@Leo - Thanks for explaining: I can understand the problem with I
(especially if Razetime's comment is correct). And thanks for demonstrating how to solve it.
@Leo - But I'm still having trouble parsing the inference. If id
is being applied to revnum
, then why aren't they grouped together with parentheses in the inference explanation (like: ((id)(revnum))
)? Instead, it looks like id
is grouped with com((predN)(any))
which I can't figure out, and it isn't clear what function any
is using at all...
