Just as a side-note, isn't the do/end construct, as encountered throughout 
the manual, PIL and representative LUA code for hiding local variables (i.e. 
used solely to limit the scope of those variables, not for looping or 
'goto'-ing), also a misused iteration construct? Not that I mind terribly 
much, but if we're going into a discussion about principles... :P
