Normally #copy should copy the AST. But it might not copy all the things related to start/stop.

Yes #copy, copies not all stuff. That's why I need #deepCopy but it just crashes image. And #veryDeepCopy works veeeery slow.

I need another solution. Any suggestions? Maybe there is some kind of method that does what I want?
