Ulrik Sverdrup	836f32e769	Use vec![elt; n] where possible ... The common pattern `iter::repeat(elt).take(n).collect::<Vec<_>>()` is exactly equivalent to `vec![elt; n]`, do this replacement in the whole tree. (Actually, vec![] is smart enough to only call clone n - 1 times, while the former solution would call clone n times, and this fact is virtually irrelevant in practice.)	2015-07-09 11:05:32 +02:00

Niko Matsakis	7ab0d1ab67	Port to using the newer graph, which offers iterators instead of the ... older `each` method, but is otherwise identical.	2015-04-17 10:12:55 -04:00
