A few questions

Yes i know, but i see there no answers.

Simen Kjaeraas:
That's exactly what i mean. Foo? or Foo! would be converted into 
NotNull!Foo.

I wrote a quick and dirty solution:
http://dpaste.dzfl.pl/400079cb

Which converts this Code:

[code]
import std.stdio;

class Foo {
public:
	void echo() const {
		writeln("My Name is Foo.");
	}
}

void foo(Foo! f) {
	f.echo();
}

void bar(Foo! f) {
	f.echo();
}

void main() {
	Foo f = new Foo();
	Foo f2;
	
	foo(f);
	bar(f2);

	foo(new Foo());
	bar(null);
}
[/code]

into: http://dpaste.dzfl.pl/d9375eeb

It is not perfect, but a first step. It would be desirable if the 
dmd compiler could do something on its own.

What are the chances that something like this happens?
