Sounds reasonable, just a quick note that I'm on holiday at the moment
and generally won't be too quick.  But I guess there's no rush.  I was
also trying to improve the docs but got sidetracked at some point.
There should be already reasonable good docstrings though.

For path series what did you have in mind?  One single patch with the
whole lot?  The original history at https:://github/flub/notdb?
Something in between?

I also recall some comments about the naming not being liked much
(notdb).  I'm open to some bikeshedding on the naming if it bothers
people.  I was only aiming for something short but under a different
import name, which are probably still useful features to keep.

Cheers,
