What did you do?
Accidentally used golang.org/x/net/context
What did you expect to see?
A deprecation warning caught by our linter. Basically I think we should mark the package (or symbols in the package) deprecated so that linters would notice and automatically suggest people switch to context.
What did you see instead?
Nothing.
