Not as a wrapper, but an official Lambda runtime model. This Go release points to a much more interesting way of doing so (RPC) than what I had previously imagined (stdin/out/err).
Yeah, the problem with RPC is that there's no one RPC to rule them all, like there is with JSON or HTTP. They'll have to build RPC wrappers for each language / VM, and choose the most popular RPC packager if there's isn't one in the stdlib.
