I love toml and used it extensively, but there are definitely warts. Arrays of objects are particularly painful[0]. If you decide that a first-level singleton non-object parameter semantically belongs after a first-level object parameter, you can't do it. Which is kind of no-duh, but TOML is simple enough that you might forget that you can't do that [0] i mean this: [[abc]] param="foo" [[abc]] param="bar" [[abc]] param="baz" Edit: ok, just read the sibling comments and they totally echo my gripes. So there's something about our common issues.
