When defining multiple variables in a let block, I tend to favor the following syntax (which I learned about [here](https://discourse.julialang.org/t/tips-on-how-to-use-let-blocks-to-shadow-local-variables-and-avoid-accidentally-modifying-the-original-variable/101467/5) on Discourse, too). In the line of the `let` keyword, I only list the variables to be given a local scope, without their assigned values. And then, in the first fiew lines of the body of the `let` block, I assign their values. E.g.,

```julia
global_value = let x, y
    x = <expression-to-compute-x>
    y = <expression-to-compute-y>
    <expression-using-x-and-y>
end

```
