I chose Go because I wanted to learn it ;) In retrospect tough, I couldn't have wished for a better language to write a web server in. I especially like the opinionated handling of code formatting and memory safety (it won't let you compile if you have a unused variable for example) and the consistent error handling (I know, a lot people seem to dislike Go's error-oriented programming style).

Unused variables have nothing to do with memory safety. At most they'll take up some stack or heap space.

Memory safety is enforced in Go via best practices–like C and C++ ecosystems. However because of gc and channels race conditions happen less often in Go but there's no explicitly tooling to prevent them from happening:

You are right. I was thinking about the general fail-safety of my programs. Not letting me compile saved me from overlooking a (return) value more than once.

You could accomplish the same thing by incorporating a code checker as part of your build process.

That way you would be catching a lot more code issues then just unused imports, variables etc.
