Yes, with the intent towards the generalized message model of a
procedure query, where guarantees are only dynamic, even if that. An
example is the matching of a software system's function with the user's
(abstract) request for an action (information update).
A more general example (and more meaningful) is the one involving the
fundamental relationship between humans and their machines, to which all
religions attempt to orthogonalize themselves (Jesus doesn't first-order
care about Tunes). I speak of the metaphor used in 2001 (see
primate-and-bone ~= modern man and space-shuttle), involving the
positivistic (i.e. Descartes' positivism: 'I think ergo I am.')
paradigm, which denies the simulation of the world within the mind as a
mechanism for learning. My thoughts on this simulation (class of
thoughts) is my own motivation for the Tunes method of computing
systems. For better insight, read up on constructivism and
constructionism as meta-philosophical paradigms.

I'll look at it as soon as I get the chance...

Just one use, I assure you. Or perhaps this is simply a homo-iconic
metaphor: everything can be reduced to 'solving a problem'. The
metaphor seems as inadequate as the functional homo-iconic metaphor
(discussed below), however.

Yes, but the semantic definition of a function seems to require that a
function almost always accept and return objects of frighteningly high
order of uncountability in order to take on real importance (in a
homo-iconic metaphor), as I see it. Hmm. Then again, I could see that
passing types of continuations as messages (as well as other examples)
could result in uncountability among the homo-iconic object metaphor.
In the current machine model, I hope to address this by transporting the
uncountable structures to the machine model's implementation. Perhaps
this is possible also in a functional paradigm with reflection. Yes, my
intuition seems to agree with this tentative assessment.

Cool. I'll take a look before returning to this.

You are right by saying that everyone will want their own
metaphors/interfaces and put them into the system and be more productive
as a result. Making Tunes ready for this is something I have been
looking at lately for the machine model (for interfaces). Of course the
'interface' as a distinguishable type in our system will be rather
arbitrary with respect to the system logic.
