Personally I found it too easy to accidentally forget to check an error, or to shadow a named error return, or to create a nil error that doesn't compare equal to nil. Also to write a method that appears to mutate the receiver but which in fact copies it.

Use https://github.com/kisielk/errcheck for that.
Or prefer https://staticcheck.io/ for a larger set of checks.
fmt.Println("foo")
how about (taken from here: (https://www.reddit.com/r/programming/comments/ak305l/goodbye...):
r1, err := fn1()
r2, err = fn2()
if err != nil {
return err
}

That second example is really surprising. This sort of thing happens all the time in production when lines get moved around. Does anyone know why errcheck misses it?
Not sure about that. But https://github.com/gordonklaus/ineffassign catches that.
use an IDE
What's a good IDE for Go? Something that's snappy and fast, no Java dinosaurs please
I mean GoLand is pretty good, but I do also like IntelliJ, so YMMV if you don't like the JetBrains products. And it isn't free.
VSCode is also really good for Go, I was surprised. There are plugins that massively help with testing, syntax checking, error handling, etc. I think it actually catches more issues than GoLand!
I've tried VSCode but it seems to require you to install Go... It can't even find the declaration of a variable or the definition of a function without Go, while Sublime can.

Visual Studio Code with the official go extension is really great and snappy
