First, sys.modules is checked to see if the module was already imported. If
so, then sys.modules[name].__spec__ is returned. If that happens to be
set to None, then ValueError is raised. If the module is not in
sys.modules, then sys.meta_path is searched for a suitable spec with the
value of 'path' given to the finders. None is returned if no spec could
be found.
Dotted names do not have their parent packages implicitly imported. You will
most likely need to explicitly import all parent packages in the proper
order for a submodule to get the correct spec.

If the name is for submodule (contains a dot), the parent module is
automatically imported.
The name and package arguments work the same as importlib.import_module().
In other words, relative module names (with leading dots) work.

The decorated function is passed the module to use instead of the module
name. The module passed in to the function is either from sys.modules if
it already exists or is a new module. If the module is new, then __name__
is set the first argument to the method, __loader__ is set to self, and
__package__ is set accordingly (if self.is_package() is defined) will be set
before it is passed to the decorated function (if self.is_package() does
not work for the module it will be set post-load).
If an exception is raised and the decorator created the module it is
subsequently removed from sys.modules.
The decorator assumes that the decorated function takes the module name as
the second argument.
