Right now, not really. I think I'd go for something like this, which is quite a bit more verbose:

```swift
let lol: [String] = {
    var a = [
        "a",
    ]
    #if SOME_CONDITION
    a += ["x"]
    #endif
    a += ["y"]
    return a
}()

```

In the long run, the next revision of [SE-0330](https://forums.swift.org/t/se-0330-conditionals-in-collections/53375/22) is our best hope.
