C++ basic type wrappers
<p>I'd like to make some basic wrapper classes around simple types in C++.  Since you can't just inherit from base types like you should be able to, I'm just using a wrapper class.  The problem is, I want to be able to cast directly to that type, since that cast would be totally valid.  The compiler just doesn't let you and I can't find a way to tell it that it's ok without running a cast method which kills performance.  Is there any way to do this?</p>

<p>Here's what I have for the conversion constructor:</p>

<pre><code>class Integer32
{ 
    public: 
    Integer32(int value) { this-&gt;Value = value; } 
    int Value; 
};
</code></pre>

<p>Does the compiler know to skip that and just assign it directly from an int?  How do I test this to make sure since it's rather important...</p>
