Right, as expected, and as Anrd pointed out, this is useful behaviour.

I do like the new flat!

Exactly,. I didn't mean to imply that that's what the built-in enumerate
should do.

Cool. then again, consider this a feature request, for a nd_enumerate,
or whatever you want to call it.
I'm sorry that implimenting something like this myself is way out my depth!
