Thanks, I see.
What about traverse? Has anybody specialized it? Is possible that two actions on the same component and operation type to be pushed into the plan? I mean two pairs (c . o1) and (c . o2), where o1 and o2 are instances of the same class, maybe with different slot values. -- Sincerely, Dmitriy Ivanov lisp.ystok.ru
I tried to do some operation specialization and found that actually it didn't work very well. The reason is in make-sub-operation --- it's very hard to get operations to propagate upstream in a way that might seem obvious: If you have a sub-type of LOAD-OP, you'd most likely want to get that sub-type on the dependencies, but this won't happen without a really substantial amount of effort rewriting depends-on, etc.
Adding entirely new operations works fine, but I have not found a comfortable way to refine existing operations. AFAICT the easiest way to get that effect is to drop new properties onto existing operation types. those properties DO get passed into the dependencies.
