Proposal 2 seems to obviate proposal 1.

Proposal 1 has a problem of naming. If we use names like isNotInteger then
semantics in Prop 1  clashes with the mnemonic meaning of such a negative
guard. (A more accurate mnemonic would be isLiteralThatIsNotInteger). Proposal
2 does not seem to suffer from that problem.
