I think that Tim's suggestion of getting a document together detailing the layout of domain vectors would be a good idea. I know what most of the elements of a domain vector represent, and I assume you do as well. I hope we can cooperate to produce a document which details what we have come to understand. > | Global change to a hash would certainly cost us in execution time. > > Why does that cost more than what you have proposed so far? Lookup via hash vs. direct indexing? Over millions of iterations? Im confident the current implementation would win. There has obviously been a huge amount of effort invested in getting axioms domain representation resonably compact and fast. > | I have not yet seen anything convincing me that a change is essential. > > I was looking more for feedback than convincing you -- I don't think I > can convince you of anything. You might just suprise yourself. After all, you did manage to convince me that using a hash as doman representation is a bad idea :) Your proposing a deep systemic change. Such things must be torn apart and analyzed. Im just attempting to contribute to that process.
