Blog post: Loop fusion and vectorization in Julia 0.6

Nice blog post and I agree this is killer feature. In the “Broadcast vs. Map” section and it says, “map requires all arguments to have the same length” but I noticed in the 0.6-beta REPL

julia> map(+, (1,2), 3)
1-element Array{Int64,1}:
 4

julia> length((1,2))
2

julia> length(3)
1

which violates this rule. Is this expected or a bug?

Thanks,
Bob
