A modern programming language that makes developers happier.

kotlinlang

What feels better/more idiomatic?
```val things = getThings() orIfEmpty listOf(SingleThing())```
or
```val things = getThings().letIfEmpty { listOf(SingleThing()) }```
or does someone have a better solution?

I think the second one feels more idiomatic but the name is maybe wrong since it does not let you return anything you want like `let` generally would.

The first could even be
```val things = getThings() orIfEmpty { listOf(SingleThing()) }```
instead

There’s already an `ifEmpty`  function in stdlib.
```val things = getThings()
    .ifEmpty { listOf(SingleThing()) }```

Oh, I didn’t think it accepted a block :face_palm:

I was honestly wondering how this didn’t exist…
