@Tammas Array{T}(0) works in 0.4-dev, but I think that's why there is also
a Vector{T} typealias for Array{T,1}, so it could be Vector{T}(0) which is
slightly better IMHO.
julia> Vector{Int}(0)
0-element Array{Int64,1}
julia> Array{Int,1}(0)
0-element Array{Int64,1}
julia> Array{Int}(0)
0-element Array{Int64,1}
