    Fragility is indeed the real concern.

    From an architectural point of view I have only been trying to identify
    and CATEGORIZE mechanisms that contribute to fragility - a useful
    exercise in any attempt to improve future architectures.

    But I take your point about pressing the stateful issue. [See another
    email of mine in this thread where I draw the distinction between self-
    bounding and other-bounding state mechanisms.]

    It is surely polemic, but not purely so.

    I (and probably not a few others) regard Ken as perhaps the leading
    authority on matters such as these. If he makes a statement like the one
    I challenged here, many will just accept it as gospel. Such weighty
    credibility demands at times a correspondingly forceful challenge in
    order to spur lesser lights like me to do our own digging. And THAT is a
    constructive outcome.
