+{- This is a "referentially opaque" import (i.e. an import that is not
+   globally addressable), which cannot be imported by a "referentially
+   transparent" import (i.e. an import that is globally addressable).
+
+   This test file is used in a failing test to verify that referentially
+   transparent imports cannot import referentially opaque imports.  In the test
+   suite this file is actually imported via its GitHub URL (not its local file
+   path), so it plays the role of the referentially transparent import.  Then,
+   this file attempts to import a referentially opaque import (an environment
+   variable in this case) to verify that the import fails.
+
+   For this test file we need to select a referentially opaque import that
+   would succeed if imported on its own, so that a non-compliant implementation
+   doesn't fail this test for the wrong reason (i.e. due to the import not
+   being present).  We thus use the `DHALL_TEST_VAR` environment variable, that
+   is expected to be set when running import tests.
