Using Dynamic instead of reflection to call method by name

Using .NET-4.0, how would I use Dynamic to accomplish the following without using reflection?

     public void InvokeMethod(string methodName)
    {
        Type t = typeof(GCS_WebService);
        GCS_WebService reflectOb = new GCS_WebService();
        MethodInfo m = t.GetMethod(methodName);
        m.Invoke(reflectOb, null);
    }

The open source framework Impromptu-Interface has methods the automate all the plumbing to use the DLR to resolve really late like this. It runs 70% faster than reflection with void returning methods.

  public void InvokeMethod(string methodName)
    {
        var reflectOb = new GCS_WebService();
        Impromptu.InvokeMemberAction(reflectOb, methodName)
    }

Dynamic typing in C# doesn't provide for that - the names of the members you want to access still has to be known at compile-time. (You could create the call site yourself of course and use the rest of the machinery of the DLR to resolve things, but it wouldn't be any simpler than using reflection, and it wouldn't really be using the language features.)
