No description provided.

FYI this was pined to 0.7.0 as it seems it was causing a bug where the pyproject.toml was being wiped.

Should probably have left a comment or even better write a test reproducing the problem... 😞

Has this issue been reported upstream?

So it turns out to be a problem only when the TOML file has out-of-order tables. The spec discourages them ("Defining tables out-of-order is discouraged."), but they are considered valid.

I tried to look at tomlkit, but it has several tests for them, and it seems to work fine on its own. However, when used with dotty-dict -like it's used in PSR- we see the problem from #336, so I'm not too sure to which upstream this should be reported: tomlkit or dotty-dict...

I've added a test case in #349, to make sure we get the right behaviour in PSR (at least).
