Data races are not easy to "code review out". That is contrary to decades of experience. All you have to do in Go to get a race is to close over a for loop induction variable in a goroutine.

There is not a large difference between C and Go here. In fact, races might be easier in Go than in C, because it's easier for goroutines to close over mutable variables.

In languages like C and C++.

I haven't really seen this as a big problem in Go. I know of one vulnerability involving this, personally. I haven't gone looking though.

Regardless, I think there's a world of difference between C and Go when it comes to memory safety.

Go certainly does have problems with data races all the time. Just Google for "golang data race": you'll find many blog posts explaining common data race gotchas in Go.

Agreed.
