You don't have to declare types, but they are enforced when you do declare them. I'm not exactly how this is bad. Anyway, you can get into a scenario like you do with Python where type errors occur at runtime if you're not using a typed function. I'm fine with it, as you might expect from the fact that I'm the author of the linked post.
