Wow... Thank you, I didn't know about that. Now for the next question: how am I supposed to use it? The following documentation leaves me absolutely clueless: """This class only works with loaders that define exec_module() as control over what module type is used for the module is required. For those same reasons, the loader’s create_module() method will be ignored (i.e., the loader’s method should only return None). Finally, modules which substitute the object placed into sys.modules will not work as there is no way to properly replace the module references throughout the interpreter safely; ValueError is raised if such a substitution is detected.""" (reference: https://docs.python.org/3/library/importlib.html#importlib.util.LazyLoader) I want to import lazily the modules from package "foobar.*", but not other modules as other libraries may depend on import side effects. How do I do that? The quoted snippet doesn't really help.
