This is somewhat tangential but related: when writing polytope code, I decided that vertices would be returned as lists, rather than vectors, precisely because of this sort of issue. Currently the lattice polytopes have vertices that are vectors, so things are a bit inconsistent.
Anyway, it would be nice for vectors to be better supported, but it seems like a difficult task to me - getting things like scipy/numpy to play nice with them, for example, seems tough. -M.
