util.paths: Optimize path joining with few arguments A casual search suggests that the majority of paths.join() calls involve only two arguments. This saves the creation of a table for up to 3 arguments. Looks like 3x faster for 3 arguments or less, 5% slower when it uses the array to concatenate.

    "JSON Test Pattern pass3": {
        "The outermost value": "must be an object or array.",
        "In this test": "It is an object."
    }
