New error message

I guess we need some way to deal with
`(addcarry₆₄, [((#3 *₆₄ #7) >>₆₄ 32), (addcarry₆₄, [(#20 +₆₄ #26), (#3 *₆₄ #7 *₆₄ 2^32)])])`
≠
`(addcarry₆₄, [(((#3 *₆₄ #7) *ℤ 2^32-1) >>₆₄ 64), (addcarry₆₄, [(#3 *₆₄ #7 *₆₄ 2^32-1), (((#3 *₆₄ #7) *ℤ 2^64-1) >>₆₄ 64)]), (addcarry₆₄, [(#20 +₆₄ #26), ((#3 *₆₄ #7 *₆₄ 2^32-1) +₆₄ (((#3 *₆₄ #7) *ℤ 2^64-1) >>₆₄ 64)), (addcarry₆₄, [(#3 *₆₄ #7), (#3 *₆₄ #7 *₆₄ 2^64-1)])])])`
