Hi!

Is it possible to make `zip()` work on a `Tuple` of `Array`s or to expand/destructure a `Tuple`?

I have a function returning a `Dictionary` but I would like it to instead return 2 arrays (keys & values) in case I don’t want a `Dictionary`:

```julia
function myfunc(...) 
...
   return array_1, array_2
end

```

And I would like something like this to work:

```julia
my_dict = Dict(zip(myfunc(...)))

```

or:

```julia
my_dict = Dict(zip(expand(myfunc(...))))

```

Is there something like `expand()`? I couldn’t find it in the Docs.  
Thanks!

You can say `Dict(zip(myfunc(x, y, z)...))` or `Dict(Pair.(myfunc(x, y, z)))`.

The `...` here is the [splat](https://docs.julialang.org/en/v1/manual/faq/index.html#...-splits-one-argument-into-many-different-arguments-in-function-calls-1) operator which will call `zip` with the individual elements of the tuple `(array_1, array_2)` returned from `myfunc`.

It works! Thanks for the speedy response!
