I'm a little bit concerned because the last package that Google seems to have purpose-built for Go+Google (AppEngine?) was context, that gave us things like context.Context, a generic KVS that needs reflection, heavily relies on convention and doesn't work in linear time and "just make every function take a context and use context.TODO if you don't need it".

It also seems to be one of the biggest points of controversy for Go 2, with calls from "everything should have a context" to "context should go away".
