The JSON spec explicitly allows parsers to accept input that isn't part of the spec but whose intention is clear and non ambiguous.
Beyond purism, why does this actually matter?

I was porting code from python standard
jsontoujsonfor better performance, and the code relies onloads("0012")to fail.bwoodsend commentedon May 17, 2023
You're probably better off going with orjson then. They take the opposite stance to us on accepting non standard inputs.
