Looking back at that code definitely brings back memories. As a consumer of both frontends, I will say I much preferred working with Clang's. Both needed extra work on top to support everything we needed. Maybe I'm just not as acquainted with C as I would like to be. It's cool to look at this again, though.
> The style of interpretation it uses—walking the AST directly—is good enough for some real-world uses, but leaves a lot to be desired for a general-purpose scripting language.
Sometimes it's useful to teach progressively, using techniques that were used more often and aren't as much anymore, rather than firehosing a low-level bytecode at people.

Try this out, you can actually (technically) assign a variable to `continue` like:
let x = continue;
Funnily enough, one of the few things that are definitely always a statement are `let` statements! Except, you also have `let` expressions, which are technically different, so I guess that's not really a difference at all.
(edited to not assume anything)
Is there a general way to apply/remove/act on taint in Go checkers? I may not be digging deeply enough but it seems like the example just uses some `unsafeVars` map that is made with a magic `isUserInputSource` method. It's hard for me to immediately tell what the capabilities there are, I bet I'm missing a bit.
I appreciate being able to choose which side of the tradeoff (always-copy or heap allocated) you want to be on, but either way be assured it's safe. Not sure how I feel about it in practice without trying it, though :)
