Even the laziest programmer is going to want to wrap the error with another error, and usually you will want to do more than that.
You can put that in-band, with something like:
v := funcWithError()? err := {
return fmt.Errorf("lazy programmer wrapping: %w", err)
}
But in that case what have you really gained?Or you can do some kind of magic to allow it to happen out of band:
// found somewhere else in the codebase
func wrapErr(err error) error {
if err == nil {
return nil
}
return fmt.Errorf("lazy programmer wrapping: %w", err)
}
v := funcWithError()?(wrapErr)
But that's where you start to see things hidden.
