Aplaud everybody! :-)
Yes, this is IMO the best way to do this.
Restrict the variables as much as you can.
There is only one case when you have to be carefull. If you define a
procedure within the same block you efectively create a closure, the
procedure will have it's own copy of the variable. Which may be what
you want, but you should be aware of that.
