This would be wrong.  The correct scope rule is that i's and j's scopes
extend to the end of the scope in which the for() statement appears. 
Consider the example

doFoo()
{
	{
		for (int i = 0; i < 100; ++i)
			for (int j=0; j<i; ++j)
				doSomething(i,j);
		...
	} /* scope of i and j ends here */
} /* definitely NOT here */

It's been my experience that this feature causes confusion.
