You are right thats not illegal . Care to try out doc to find out 
whats wrong ? 8)

Hint:
{
<no previous definition of i>

	for (long i = 0....) { // first definition of "i"
	}


<Any reference to "i" from this point on is outside the scope of the
definition i.>

<for instance the following reference to "i" is illegal>
	 var.ref(i)

}

	Regards,
	Amancio
