Does elvis operator work with boolean checks? I currently have `remote.foo != null &amp;&amp; remote.foo != local.foo` I’m trying to simplify it to something like `remote.foo != local.foo ?: false` but it seems like the elvis operator can’t be used that way

nukeforum: no. The Elvis operator doesn't work this way. Meanwhile, you can just do `remote?.foo != local.foo`

nukeforum: However, a close replication of your example could be: `remote?.let { it.foo != local.foo } ?: false`

so, `local` and `remote` are non-null, but in either case `foo` is nullable. I need the entire check to default to `false` if `remote.foo` is null without having the entire separate clause to check it

ah, yeah, I thought about using `let`, but it ends up being about the same amount of characters :sweat:

Ah. Sorry. I missed that.
Doesn't look like you have much options

If it were to be in a function though, one could split this into 2 lines and have something like this:

```
fun checkFoo(remote: Bar, local: Bar) : Boolean {
  val remoteFoo = remote.foo ?: return false
  return remoteFoo != local.foo
}
```
