One of the "problems" with adding nested functions to C is the addition
of a display to access autos in outer scopes. The whole issue could be
avoided by not having autos imported into functions.
E.g.:

	int f( int a )
	{
		static int b;
		auto int c;
		int g( int d )
		{
			b = d+1;	/* is okay */
			c = 0;	/* error: c is not in scope */
			return d * b;
		}
		c = g( a + b );
		return 3 * c + 2;
	}
	/* g is not visible here */

This results in scoping rules similar to Port (a cousin of C -- B->Zed->Port,
I believe).

Additional idea:
	an auto function is not visible to inner functions, static function is
