If you want absolute certainty in your types with TS, you should be using the `--strict` flag, which makes it so this is not the case.

"absolute" is a bit of a funny qualifier to use here, given the many soundness holes in TS.

For example (included with --strict):

(I like TS, I just don't think it fully solves this problem!)
