[go] inconsistent highlighting of imported package names

[takamori]

The following content will have inconsistent highlighting of "status". Ideally "status" would always be highlighted.

package foo

import (
	"testing"

	"something/status"

	resp "something/else"
)

func Test(t *testing.T) {
	r := &resp.Structure{
		Name: "exist",
	}

	tests := []struct {
		name      string
		errStatus status.Code
	}{{
		name:      "test",
		errStatus: status.OK,
	}, {
		name:      "exist",
		errStatus: status.InvalidArgument,
	}}
}

Though the Go grammar treats qualified identifiers differently from selectors, they look the same and I can't find how they should be disambiguated, so it seems reasonable to treat foo.bar in expression context as a variable name followed by a dot and a property name.

For types, there are only qualified names, so there the mode does treat the part before the dot as a package name—calling it a variable there would be nonsense.

If you have a suggestion on how to do this differently I'm interested, but as far as I understand Go treating every identifier followed by a dot as a package name would be wrong.
