Like JS from which it sprang, it lacks an integer type. Fortunately, parsers written for languages that do have integers can usually parse them correctly. (If you don't know why this might matter, try opening your browser's Javascript console and evaluating 10000000000000001) That's my peeve, though. I suspect that Tom is probably more concerned with readability. TOML also looks like it can be parsed a line at a time and doesn't really need to do any recursive parsing, so you could probably parse a stream of it as it arrives, which I imagine is trickier with JSON.
