Hi Nick,

I think yes ;-)
I would like to use (or I think it would be good to use) something like
pathlib.Path(package_root)
so I could use

importlib.import_module(pathlib.Path(package_root) / plugins / plugin_name)

and normal file system operations (for example)

with open(pathlib.Path(package_root) / plugins / plugin_name) as my_file:
    do_something_with_file


Import statement can be used to go downward and path can be used up and
down in the directory hierarchy. If someone wants to use both of them, the
only common point (branch) is the package root. From the package root one
can use the same path expressions for import and for other file system
operations.


BR,
George
