title: How do I instantiate a class from its TRttiType?
body: <p>I want to create a form given its class name as a string, <a href="https://stackoverflow.com/questions/701049/is-there-a-way-to-instantiate-a-class-by-its-name-in-delphi">which has been asked about before</a>, but instead of calling <code>GetClass</code>, I want to use Delphi's new RTTI feature.</p>
  
  <p>With this code, I've got a <code>TRttiType</code>, but I don't know how to instantiate it.</p>
  
  <pre><code>var
    f:TFormBase;
    ctx:TRttiContext;
    lType:TRttiType;
  begin
    ctx := TRttiContext.Create;
    for lType in ctx.GetTypes do
    begin
      if lType.Name = 'TFormFormulirPendaftaran' then
      begin
        //how to instantiate lType here?
        Break;
      end;
    end;
  end;
  </code></pre>
  
  <p>I've also tried <code>lType.NewInstance</code> with no luck.</p>
