// this module.
// ["//some/package:__pkg__", "//other/package:__pkg__"]: Only modules in some/package and

// this module. Note that sub-packages do not have access to the rule; for example,
// //some/package/foo:bar or //other/package/testing:bla wouldn't have access. __pkg__
// is a special module and must be used verbatim. It represents all of the modules in the
// package.
// ["//project:__subpackages__", "//other:__subpackages__"]: Only modules in packages project
// or other or in one of their sub-packages have access to this module. For example,
// //project:rule, //project/library:lib or //other/testing/internal:munge are allowed
// to depend on this rule (but not //independent:evil)
// ["//project"]: This is shorthand for ["//project:__pkg__"]
// [":__subpackages__"]: This is shorthand for ["//project:__subpackages__"] where
