bazel-skylib/tests/sets_tests.bzl
Thomas Van Lenten b5f4086001 Remove usage and suggests for lib.bzl.
As more things are added, lib.bzl is an anti-pattern as the cost of loading
it actually just keeps increasing and most things will never use everything
out of it.  The pattern the should be used is to directly import the modules
one uses.
