> You don't build error handling classes in Go.

I've encountered people doing this. When I said "If I had Maybe here then I could write 1/5 as much code," someone showed me a class that maintained whether it had encountered an error, and each method would do nothing and return the previous error if so. This allowed him to write 1/5 as much code in the method that actually does stuff, just as he would in Haskell or Swift. Unfortunately the approach of reducing every function full of noisy error checking to a bunch of calls on one object is pretty bad in general...
