            Heh, yes, damned if you do, etc. etc. I was trying to think up a practical example where this would cause problems (e.g. in CSS libraries strings and numbers often mix), but all my cases involved an `=-using third party library, in which case you'd just pass it `Number(myLong)` instead of `myLong` directly and move on with your life.

        Wait, number works:

        js>  0L =0
        true
        js>  0L + 1
        1L

        Are you thinking of string?
