Is there any way to check whether two syntax objects have the same lexical information, syntax-e (recursively), source location, properties, and whatever else they have, even if they aren’t eq?

For the syntax-e and source-location this is straightforward, but if there’s no accessor for the lexical information then how do I check if the lexical information is the same if the syntax objects aren’t eq?

And for the properties, can you only check the properties with keys that are interned symbols?
