Unrelatedly, have the Julia devs decided to require variable declaration yet? E.g. "local x = 1" instead of just "x = 1"? Or better yet, "x := 1"?<p>How many times does this mistake have to be repeated in various languages? It'll just be a matter of time before people are banging on for a strict mode, and rightfully so.<p>At least the default scope in Julia is local. :/
