It may be subclassed for compatibility with legacy third party
reimplementations of the import system. Otherwise, finder
implementations should derive from the more specific MetaPathFinder
or PathEntryFinder ABCs.

The fullname is a str. The namespace portion is a sequence of
path entries contributing to part of a namespace package. The
sequence may be empty. If loader is not None, the portion will
be ignored.
The portion will be discarded if another path entry finder
locates the module as a normal module or package.

is provided than backwards-compatible functionality is provided.

ResourceLoader and ExecutionLoader need to be implemented. To also support
loading from bytecode, the optional methods specified directly by this ABC
is required.
Inherited abstractmethods not implemented in this ABC:
