I feel that the difference between homogeneous and heterogeneous arrays is a very important distinction, and not some odd thing that you might only rarely care about. The distinction has a massive impact on speed. The point of Julia is to be a fast dynamic language. Hiding the distinction under the carpet seems contrary to one of the aims of Julia. Ivar's suggestion of: @assert isleaftype(T) is nice, but it doesn't feel quite right to me.
