This will be separated when we'll start to generate helper
expressions for actual instantiation of all private variables.
This is a temporary solution.<br>

This is from the standard:<br>
<blockquote type="cite">Certain variables and objects have
predetermined data-sharing attributes as follows:<br>
...<br>
<ul>
<li>Variables with automatic storage duration that are
declared in a scope inside the</li>
</ul>
construct are private.<br>
...<br>

<blockquote type="cite">
<pre wrap="">Also with this: We should say "Must be shared because ..." and tell the user why.</pre>

Agree, though there is a lot of work to do it. I think we should
prepare a separate patch for improving error messages.<br>

We should separate the errors for not having an accessible copy constructor vs. having an ambigious one (for which we should make sure we note the alternatives).
