I note that, like many erstwhile specs, TOML does not document the escape sequences accepted in strings. Nor does it exhaustively specify integer formats and float formats - rather ironic for a spec that advertises "TOML is designed to be unambiguous and as simple as possible."

The limitation on array types seemed fairly arbitrary at first glance, but after thinking it over I realized it aided compatibility with languages that do not support homogeneous arrays. Though as far as the types go, I would add boolean and perhaps non-quoted strings for single-word values.

Now that the technical criticism is out of the way, holy crap this guy is arrogant.
