? repetition causes matched nodes to be returned as an array

The pattern is reduced from what I'm trying to write. I'd like to use OR {} but because each branch will contain different amount of captures, I write multiple ? matchers after each other. * and + can return 0-n and 1-n matches so it totally makes sense to return an array for these. + on the other hand is ony 0-1 so I'd expect this to be either be the node or nil.

Can't change this now without a major version bump of course and the solution for me is to just call flatten somewhere in the code but I wanted to see what others think. Does my "complaint" make sense?

It does.

Well, there's a major version in the works... :-)
