The $var inside the { } is lexically scoped to that block, and cannot be
seen outside of it. If you want both a $var inside the scope and one
outside the scope, you should declare the one inside the scope with
'local' (intead of with 'my'), so it doesn't tromp over the global $var.
But they are still two distinct variables.
