You know, I've heard this a few times recently and it strikes me as motivated reasoning. Yes, built in unit testing and tooling is great. Vet and fmt are helpful. Static typing rocks. But... I would definitely welcome a proper debugger.

I'll be candid with you: You're probably right. I would also welcome a debugger in the long run, and I'm sure I'd change my tune pretty quickly if I hit a big snag in production. :-)
