I would just like to remind, that directories with union mounts do
present "inheritance". Because inheritance is the most defining
characteristic of the OO paradigm, is is quite fair to say that file
systems in Plan 9 are (persistent, networked) "objects" in the
classical OO sense.

You can take a standard /net and bind your own modified /net as an
union with it, hiding some files, replacing some files, and leaving
some files intact. That is, you can take a father object, inherit some
of its functionality to the child object (the union) untouched, modify
some functionality (perhaps filtering ctrl files and writing back to
original ones), and remove some. Exactly like in SmallTalk or C++ or
Java.
