If it gets in as-is then we'll have to live with the IMHO broken API
(yet another one besides the existing double-int). So _please_
shrink the API down aggresively in favor of using non-member
helper functions with more descriptive names for things that
lump together multiple operations. Look at double-int and
use the same API ideas as people are familiar with it
(like the unsigned flag stuff) - consistency always trumps.
I'm going to be on vacation for the next three weeks so somebody else
has to pick up the review work. But I really think that the tree
has to recover from too many changes already.
