Ok, I think I solved this with `whileSelect`, but what's the boolean that needs to be returned for? It doesn't look docuemented in the guide's examples..?

`whileSelect { ... }` is a shorthand for `while(select { ... }) {}`, so the value of the boolean result is self-explanatory.

You mean it doesn't exit the loop until it's true? And select by itself returns whatever result it gets from the first onXXX that gets called? I looked through the kdocs and the guide, and I don't think I saw something talking about this, unless I missed something?

```Loops while select expression returns true.```

Thanks! I was looking at the guide (finally noticed that there were changes from the last time I read it... I think I'll have to go through it again...), and the onXXX functions, I hadn't realized that `select` itself returns those results... When Roman showed that piece, it dawned on me, especially since whileSelect isn't mentioned in the api overview, you really have to look for that page.
