In my experience this isn’t idiomatic Go and would definitely turn heads in a code review. But in such a small function, it’s fine to just not worry about the lifetime of your variables (and in bigger functions you can often decompose into smaller functions).

I agree. The idiomatic thing here would be to simply declare `var err error` in the surrounding scope, especially since this example is a small function where this wouldn't matter.

But "idiomatic" always takes a backseat compared to technical necessity. If there is a requirement, for some reason, to limit the scope of `err` and still allow `result` to be changed in the if's pre-assignment, then this is the way to do it.
