"You won't make mistakes if you remember not to make mistakes" is nice in theory, but just not how people work in real world. Just like trivial syntax errors are very common while you're doing things. It's better to embrace the common human failures and have a second layer of protection.
I explained in my other comment how it's a great tool for other jobs, but the wrong tool for this job. You won't learn how not to break things by ignoring the proper tool.
