JSON mandates double quotes, even though JS and Python both support
single. Python's built-in float won't repr like that. Add all that
kind of thing together, and you get my original conclusion that this
is JSON. It's also perfectly parseable as various other things, but
it's still most likely to be JSON.

... JSON doesn't actually mandate that. You can use any top-level
type. The string '"hello"' is a valid JSON-decodable value.
