Thank you to everyone who responded to yesterday’s pop quiz! I got a number of responses, both by email, and on LinkedIn and Mastodon. And the majority of responses made the exact same mistake I made, and assumed the code was invalid, because a is referenced before it’s initialized: var x = a var a = 3 And while it’s true that this is an error within a function, much to my surprise, it’s actually completely valid in package scope, as we’ll see now.
