Unfortunately, this very function:

        h(word) = leng(word) + value(firstletter(word)) +
                value(lastletter(word))

fails if the input is 68000 opcodes, which is my need for hashing.
In particular, BNE, BLE, & BGE all have length=3, firstletter=B, lastletter=E.

Oh well.  I'm sure I can come up with another function.
