Different animals. How would optional (or, for that matter, named) parameters help here:

public class WhatEver
    {
        public void DoSomething(string a) { }
        public void DoSomething(int i) { }
    }

OhOh Michel - something wrong with the pre tags. What I actually wrote (in tags) was:

public class WhatEver
{
public void DoSomething(string a) { }
public void DoSomething(int i) { }
}

UPDATE for Michel: This looks OK in the posted version but in 'preview' although the code segment showed up with the white background it had a bunch of embedded span elemtents ?
