Oh yes, no problem. Any help with revv'ing that struct (or with other
parts of the code) is very much appreciated. Feel free to make any
changes necessary on the branch.

Yes. I guess I (or whoever takes a look at it) should go through the
docstrings (and inline comments) to see if they still describe things
accurately. Most of those date from the initial implementation on the
branch, so may be slightly out-of-date.

If I have some time, I'll try to take a look at it.
