This is a bit backwards. Vector{Any} is a subtype of Vector, of course!
Perhaps I was expecting too much. I was envisioning a list containing 'any'
sort of elements, and that would include vectors with all types of
elements. After checking I see that numpy arrays are not a subclass of
list, so Vector{Any} is sort of analogous to python 'list'. It just
requires some extra thinking to realize that Vector{'anything'} is not
included in that group.
