Hello Gus!

I was pondering a similar problem when I posted [this suggestion](https://discourse.julialang.org/t/proposal-to-extend-the-syntax-of-list-comprehensions-with-a-let-clause). Based on [this answer](https://discourse.julialang.org/t/proposal-to-extend-the-syntax-of-list-comprehensions-with-a-let-clause/87256/9), your contrived loop can be rewritten in list comprehension syntax as follows:

```plaintext
out = [rand(s)[1]
       for i in 10:2:30
       for t = Ref(randperm(i))
       for s = Ref(maximum(t))]

```

Whether you prefer this, the for loop or the map syntax is a matter of taste.

HTH.
