 So would anyone be especially opposed to making best leftmost an
 explicit requirement, enforced by repoman where possible (at least for
 the = /  case)?
 
 I already thought that was the case, so +1 from me.

Me too, but can't tell where I picked that up. +1 anyway.

 This is the same kind of case as in bug 264434. We solved it in
 portage by putting || and virtual dependencies on stack, and delaying
 their evaluation until as late as possible. You may be able to dream
 up some corner cases where this approach doesn't help, but in
 practice it seems to help more often than not.

That's just another case where a fancy heuristic sometimes gives you
better results, but in general doesn't solve the problem at all. If
you've got two lots of undecided || ( ) deps, sooner or later you have
to decide at least one lot, but you can't correctly make that decision
until you've decided the other lot (which of course then can't be
decided until you've decided the first...).

We're all having to be way too clever here, and it isn't even helping.
