Right, I think it is as simple as the using declaration, but also includes a revision to the coding standards and programmer manual dox.

I do think that renaming SmallVectorImpl to VectorImpl would make sense, that is something we can stage in over time (introduce the alternate name, rename everything in tree, then drop the old name in a few months).
