"""Package context mirrors and amends Go package context.

 - `Context` represents operational context that carries deadline, cancellation
   signal and immutable context-local key -> value dict.
 - `background` returns empty context that is never canceled.
 - `with_cancel` creates new context that can be canceled on its own.
 - `with_deadline` creates new context with deadline.
 - `with_timeout` creates new context with timeout.
 - `with_value` creates new context with attached key=value.
 - `merge` creates new context from 2 parents(*).

See also https://golang.org/pkg/context for Go context package documentation.
See also https://blog.golang.org/context for overview.
