Ah, I think I know where my confusion sprang from after having discussed
this on IRC. I'm fairly used to various overloaded uses of language in
metaphor and other parts of rhetoric, so I was expecting that the terms
might in some way offer some clue as to the nature of the concepts to
which they were attached. However it appears, to me anyway, that the
words themselves are completely opaque: there is absolutely no
connection I can determine between the words and the concepts that they
Having realized this and now I'm not struggling to find some meaning in
the terms themselves it all becomes much clearer.
I'd still like a nice self-sufficient paragraph that explains the ideas
without reference to some example code though.
