isLenient

var isLenient: Boolean(source)

Removes JSON specification restriction (RFC-4627) and makes parser more liberal to the malformed input. In lenient mode, unquoted JSON keys and string values are allowed.

Example of invalid JSON that is accepted with this flag set: {key: value} can be parsed into @Serializable class Data(val key: String).

Its relaxations can be expanded in the future, so that lenient parser becomes even more permissive to invalid values in the input.

false by default.
