Well I don't know much stuff about GC and internals and if you 
think it is not a good design concept, ok I'm fine with it. I 
don't "miss" C#'s using statement or IDisposable. I was just 
giving a suggestion that would be discussed and considered with 
the community.

At least this with(declaration) syntax might make it into the 
language. And probably use the more "strange" one, where you only 
give it an rvalue:
with(new Foo) {
     name = "Foo"; //same as temp.name
     calc(); //same as temp.calc()
     writeln(); //and even maybe this to be translated to 
temp.writeln() and then to writeln(temp) ?
}

Well that was everything I had to say about with, using, and 
dispose. I'm glad that there was a discussion going.
