I'm trying to decide what to do with this series; probably nothing for
2.10.

These, I would have considered. But it seems Richard had an alternative
idea which is 2.11 material. So I'll probably just ignore these for now.

This is certainly 2.11 material.

That one tells me that I really should try to get an understanding of
tcg...
