Could you elaborate on the confusion, please? Not necessarily for the glossary,
but ... well just curious.

Other definitons are welcome, of course, but what's unclear about this one?
I would prefer not to import
all "software component" connotations.

It would be easier if you'ld just write something cut&pastable. Not just because I'm lazy (I am) but because it's the faster road to quality content. This goes for everybody else too, of course.

No. It was deleted per quotee request.

This is a very interesting and important topic in itself. I hope to go into it later. For starters: objects(2) behave. Stored things do not behave.

Thank you. I'll wait for now.
