No, scopes are rewritten with compiler to something like this:

```

	void test()
	{
		writeln("test");

		try{
		
			try{
				throw new Exception("exception");
			
			}
			finally{
				writeln("exit");
			}
		}
		catch(Exception ex){
			writeln("failure");
			throw ex;
		}
	}
	void main()
	{
		try
		{
			test();
		}
		catch (Exception e) writeln(e.msg);
	}
```
