Thanks for the idea, Achim, but I don't think a JSON-RPC library should be
in the stdlib. Honestly, if someone was proposing an XML-RPC library to go
into the stdlib today I would argue for it not to be included. I don't
think JSON-RPC is used by the vast majority of Python users nor difficult
enough to implement correctly to warrant being in the stdlib.
And even if we thought a JSON-RPC library should be included, I would argue
it should be asynchronous, meaning that the xmlrpc library couldn't be
reused in any way for the implementation.
