If you want to iterate over several Foo objects you can put them in an array 
like this:

Foo[] fooArr = [ new Foo(1), new Foo(2) ];
foreach(Foo foo; fooArr)
    foo.i++;

If you want to iterate over every Foo ever created, you will need to do
something 
else (like have the constructor keep a list of Foo objects it has created).

That would be one options.
