I recently published a short note on this topic in Information
Processing Letters. It would be interesting to know what Larch folk
think about my comments. (Please e-mail - I'mm about to be away from

        author   = "C.B. Jones",
        title    = "Partial functions and logics: A warning",
        journal  = ipl,
        volume   = 54, 
        number   = 2, 
        pages    = "65--67", 
        year     = 1995
