Why doesn’t this throw, given that the array `[10, 20]` is one-dimensional? I would expect a `MethodError`.

```julia-repl
julia> [10, 20][1, 1, 1]
10

```

This is documented:

Probably it wouldn’t hurt to have a short explanation of why that’s convenient. I remember reading discussions about that here.
