in thread annotation, derivation

Cool, that looks very much like what I hoped for, I'll have to have a play to see if I can find a sensible way to record and expose the locations and stacktraces at which the calculations occur.

Getting the information to survive across transitions to string and back may be harder: in fact, I suspect sensible string support will generally be rather harder (eg to extract the interesting information from something like $string = join ', ', @substrings).

I wouldn't have gone for an lvalue derivation(), but I think that's more an issue of personal style.

    Object::Stash is written in such a way that, the accessors can be used as lvalues, or getter/setters:

    $quux->derivation = 'x'; $quux->derivation('x');

    ... are both equivalent.
