Please, quote your code with triple backquotes: Discourse is doing lots of automagic rendering, it took me a while to figure out was an empty vector `[]`.

The fact is that [`push!`](https://docs.julialang.org/en/v1/base/collections/#Base.push!) returns the collection you’re pushing to, so each element of the [comprehension](https://docs.julialang.org/en/v1/manual/arrays/#man-comprehensions) is `arr`, so the final result is

```julia
[arr, arr, arr, arr, arr]

```

with `arr` being

```julia
Any['f', 'l', 'a', 'r', 'p']

```

Also, note that you are getting _a_ vector at the end, but it’s a vector of vectors
