Is there some way to implement map function with two arguments where one isn’t an array, without creating a new array, since it can be too large.

Here is a very simple example of an idea.

> map(+,[2,3],1)

Are you looking for `broacast`?

```julia
julia> broadcast(+, [2, 3], 1)
2-element Array{Int64,1}:
 3
 4

```
