[issue21617] importlib reload can fail with AttributeError if module removed from sys.path

[Michael Forbes]

Michael Forbes <mforbes at users.sourceforge.net> added the comment:

It seems that a reasonable workaround (if you generate your own `spec`) is to call `spec.loader.exec_module(mod)`.  This seems to reload the module into the same namespace. (I was afraid that it might replace the namespace hence the desire to use `importlib.reload()` explicitly.)
