It's overloading the invoke( () -&gt; { }) operator with a trailing clojure.... Which may be confusing in itself so opinions are welcome

arocnies: Since the block is acting on a `FileBrick` and not a `String`, I'd say just leave it as it is.

I saw your comment about `"foo".state = ...` but I can't find it now.

I misread your comment and gave bad advise, so I deleted it. Sorry for the confusion.

Oh no worries. That actually looks  like a potentially good option to me. Maybe I'm missing  it's cons?

With my deleted suggestion, you would no longer be operating in the context of `FileBrick` so you wouldn't have access to `state` or `copyOf`.

Also, since the `FileBrick` is created in the block, creating a `var String.state` wouldn't work since you can't really define a logical getter for it.

Unless I'm wrong in assuming `state` is a property of `FileBrick`. If it isn't, there could be clean ways to do it.

`state` is a property of `FileBrick`. Hmmm. I think it's starting to make sense. I think I need to experiment a bit to fully understand the implications of using String.state

Ah okay. Now I think I understand what you mean.

I did find a way to make `file {  "/etc/foo".state = copyOf("foo")  }`

But it's messy. And now using an infix function looks better. Thanks for the help. I'll probably keep it as it is for now
