Yes, but it also makes the whole thing less flexible and more brittle (as we have found, to our cost), by removing that extra layer of binding (indirection). Remember Lampson's famous dictum about 'most problems in computer science can be solved with another level of indirection'.
But doesn't the dictum continue: "...but usually this will create another problem?" ;-) Anyway, I completely agree with you that the advantages of having an ID/locator indirection more than outweigh the costs. - Christian -- to unsubscribe send a message to rrg-request@psg.com with the word 'unsubscribe' in a single line as the message text body. archive: <http://psg.com/lists/rrg/> & ftp://psg.com/pub/lists/rrg
