digitalmars.D.learn - static functions?

[code]
class foo {
	public static int bar() {
		return 0;
	}
}
[/code]

How do I call bar() without creating an instance of foo? 
foo.bar() results in "Error: undefined identifier 'bar'"

I'm having a really hard time finding anything related to D in 
general.

What am I missing?

When you write "import foo;" and then foo.bar, the compiler 
thinks that
you a referring to a global function bar in module foo. To call 
static function bar of class foo in module foo write 
foo.foo.bar(). Or you could write "import foo : foo;" to import 
just the class foo from module foo and not the entire module.

Or even better, name your module foo.d, and name your class Foo. Then...

import foo;

void main()
{
     Foo.bar();
}

That's also the general convention.
