I found this behavior surprising: julia> using Iterators: product julia> p = product(1:2, 1:2) Iterators.Product{Tuple{UnitRange{Int64},UnitRange{Int64}}}([(1:2, 1:2)) julia> [1 for x in p, y in 1:2] 8-element Array{Int64,1}: 1 1 1 1 1 1 1 1 julia> [1 for x in collect(p), y in 1:2] 4×2 A…

I think this is intentional. It’s not possible to compute the shape ahead of time for length-less iterators like the Iterators.Product from Iterators.jl.
