I think perhaps I'm not expressing myself very well.
What I'm after is a high-level explanation that actually
tells people something useful, and *doesn't* cop out by
just saying "you're not experienced enough to understand
this yet".

If such an explanation can't be found, I strongly suspect
that this doesn't correspond to a cohesive enough concept
to be made into a built-in language feature. If you can't
give a short, understandable explanation of it, then it's
probably a bad idea.
