-Imports that we need at runtime, but might not be present.
-
-When importing one of these modules, always do it in the function where you
-need the module. Some tests will need to remove the module. If you import
-it at the top level of your module, then the test won't be able to simulate
-the module being unimportable.
-
-The import will always succeed, but the value will be None if the module is
-unavailable.
