I am real noob about grammar description languages so I need some
explanation about it. As far as I understand expressions in curly
bracers are used to modify syntax tree just in process of parsing
instead of modifying it after?

OK,that's clever. But I get this even when put a writeln("some msg")
inside the task. I thought a write couldn't be optimized away that way
and that it's a slow operation?
Anyway, I discovered Thread.wait() in core in

Because
