title: Simple types with generics in Delphi
body: <p>How can I create a generic class only containing primitive types?</p>
  
  <pre><code>TField&lt;T: xxx&gt; = class  
  private
      FValue: T;  
  public  
      property Value: T read FValue write FValue;  
  end;
  </code></pre>
  
  <p>I don't need interfaces, classes, etc, I only want booleans, ints, floats and so on...</p>
  
  <p>Or there is another way to do that?</p>
  
  <p>Thanks</p>
