Thanks Pádraig, excited to see this making its way into the mainline.

Can't you store field specifications as the elements in an avl tree as
well, without having to resort to something fancy like an interval
tree?  And if it's the same number of elements, shouldn't memory
consumption be the same as with a linked list since they're both node
based structures?

I went with the avl tree just because theoretically if someone were to
list duplicate, out of order fields (or field specs) inserting them is
going to be O(n) with a sorted linked list vs O(logn) with a binary
search tree.  Obviously for such a small cli tool it doesn't really
matter though.

I trust your judgment, just curious for my own edification.

Thanks,
Dylan
