I'm trying to extend them to several dimensions (and returning a NamedArray instead of a dict or a plain array). But I figured special-casing PooledDataVectors would be useful since most of the time that's what people will make table from -- and it makes things simpler for a start, to get more familiar with performance issues at stake. If it turns out the generic AbstractArray method is efficient enough, we can still drop it. But ATM my version of the latter has a terrible performance. Regards
