> In v0.6, I used StructsOfArrays to do broadcasting with tuple output: using StructsOfArrays T = Float64 TV = Vector{Float64} a = zeros(T, 10); b = copy(a) s = StructOfArrays{NTuple{2,T}, 1, Tuple{TV, TV}}((a, b)) f(a, b) = (a + b, a \* b) s .= f.(1:10, 1:10) A macro for the above should be simple enough. Figuring out T and TV and handling the case where a and b are not already allocated are the main challenges I can see.
