I did! I should have said it's incomplete. I ran across #70[1] which is kind of really needed for the config structure I had in mind. After that I just went back to working on other stuff...

Ah. Bummer. Interesting to know, though.

I'm kind of un-bullish on toml in general, sadly. I tried toml in a couple of projects, and found for structures nested beyond a certain level, it doesn't really seem all that simple anymore. I ended up going back to json or yaml (only with a parser that doesn't implement most of the fancy features of yaml, for conservation-of-sanity reasons, of course).

Have you seen inline tables? It solves what you mention pretty well, which is why I was looking for it for this project.
