Yes. So references to the context will return values instead of
raising an error.

I think I'm comfortable with that. There's nothing that prevents an
implementation from warning about context references when no context
is given.

Most of the time, I think users will specify the context (or get the
right default context) and when they don't, they'll almost always be
using expressions of the form "$foo" which don't refer to the context
