A modern programming language that makes developers happier.

kotlinlang

I just tried writing an extension to use `or` instead of `?:` for null coalescing and I found some interesting results.

Here's the extension:

`infix fun &lt;A&gt; A?.or(that: A): A = this ?: that`

I wrote a small snippet to validate this which works fine:

```
val s: String? = null
val a = s or ""
```

Then I wanted to test conflicts with `Int.or` and so I changed my snippet to:

```
val s: Int? = null
val a = s or ""
```

I expected an error saying something along the lines of `or expects an Int` but to my surprise it compiled fine. I plugged it into the kotlinc repl (is is technically a repl?) and printed `a`. It was an empty string :exploding_head:

Then I printed `a.javaClass` and it was `String` :exploding_head: :exploding_head: :exploding_head:

Am I missing something here? I wanted to search the issue tracker, but I can't even figure out what to search for.
