Why is TOML.stringify() output different for equivalent JSON input?

[Leftium]

TOML.parse() seems to output a JSON object that somehow "remembers" the original TOML formatting. When the JSON is sent back to TOML.stringify() the original formatting is preserved. However when this JSON is "purified" by stringifying and parsing back to JSON, the formatting is no longer preserved.

How is j-toml "remembering" the format of the original TOML? How can I force j-toml to use a certain format for object literals that are added to the JSON?

This library use WeakMap internal to remember object formats parsed by same library. For objects from JSON.parse or other way created, you may mark each object by helper functions provided by the library, because I didn't find a better way to know what coder want.
