Seems like an easy enough thing to write.  Given that AMPList doesn't use a length prefix (it uses null-key box-termination, just like the rest of the protocol) the representation would be exactly the same.  Just add a trivial wrapper that uses AMPList, unpacks its argument, and assert that there's only one of them?
