One possibility here is that we could wrap any input to pyarrow.serialize in a list (even other lists), and then unbox on deserialize

Philipp Moritz / @pcmoritz:
Yeah, that's a good way to do it; that's what we do for PlasmaClient.put and PlasmaClient.get but you are right, it should be done on the lower level of serialize and deserialize. I can create a PR.
