A functional implementation of JSON-RPC over WebSockets. GopherJS clients
should use the client package and net/http servers should use the server
package.
flynn's rpcplus implementation passes one context object to all methods called.
This significantly impacts the design of an authentication/session mechanism.
One way to design an authentication/session mechanism would be to try to make an RPC service that changed the context itself. However, contexts are designed to be copied, not mutated, and changing the type of context would be anathema to the static analysis tools that support context.
The other way is to bake authentication into the protocol directly.
