You were courageous to even try :-)
From their refusal to see any use in explicit variables declarations, their (somewhat related) huge scope debacle, to its strange and irregular 'resolution', not to mention the original absurdly weird propositions they had made to resolve it: the scope and variable declaration subject is pretty hopeless in Julia land. I quickly gave up on it years ago (long before the scope debacle), as I had no intention of losing my time, when I saw the arguments and the logic they used.
