--- Comment #17 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-03-04 13:06:40 UTC --- Probably better, yes. As aliases are cheaper to instantiate than templates it shouldn't affect compilation time or binary size to repeat it in each container, but defining it only once would be easier to maintain.
