Add name.variable and value.variable (#2219)

I think it's worth distinguishing between an assignment (`foo = bar`)
and a variable declarateion (`const foo = bar`) to make it clear we want
to support both. I think the name `name.variable` and `value.variable`
are clear enough and consistent with `name.function`
