Edwin Brady	e1c79ef07d	Better error when no alternative is valid ... Instead of guessing the error for the thing that's closest to working, better to say that no alternative works. (This makes the bizarre 'score' heuristic for error messages obsolete, so that'll be removed soon too.)	2015-07-17 23:37:19 +01:00
Edwin Brady	5da0d60564	Faster processing of alternatives ... Mostly by delaying the expensive checking for uniqueness of names until the point where we actually need the branch, thus removing a significant amount of unnecesary work.	2015-07-17 20:56:55 +01:00
