Like the author said, the weird thing is that it goes both ways. I'm pretty sure if you try to return `any` from a function with an explicit return type in TypeScript you'll get pinged for it.
noImplicitAny is different than what's being discussed (I think). Returning something typed as `any` in a function that has a different return type is totally fine: it's not implicit (you've cast it to any), and it passes (you're saying the type is literally anything after all).
