+  # provided by importlib to import test modules.
+  # This gives full control over the import process,
+  # and doesn’t require changing sys.path.
+  # For this reason this doesn’t require test module names to be unique.
+  # One drawback however is that test modules are non-importable by each other.
+  # Also, utility modules in the tests directories are not automatically
+  # importable because the tests directory is no longer added to sys.path.
+  # Initially we intended to make importlib the default in future releases,
+  # however it is clear now that it has its own set of drawbacks
+  # so the default will remain prepend for the foreseeable future.
