The scope should be unique, yes. In your example value should be visible.
Your are right about the word double braces, but I can't think of an alternate syntax other than just removing the braces around the while. But in that case it may seem odd to have a keyword that can only be used inside a specific block...wich is basically a macro for a if(.)break;
Maybe I'm too used to the c/java syntax, maybe with a different way of defining blocks?
