Effective Error Handling in Golang
I want to add that when wrapping error you should add function name you've called not function name you are in. Caller of your function already knows what he is called and he'll wrap it if he needs to. Or even better use human message and function name you can get out of Program Counter attached to the error. Non-stdlib errors package can do that (I use my own).

When comparing new and errors you can also consider the following projects:
pointer - Go package pointer provides helpers to get pointers to values of built-in types.
errors - A drop-in replacement for Go errors, with some added sugar! Unwrap user-friendly messages, HTTP status code, easy wrapping with multiple error types.
spidy - Domain names collector - Crawl websites and collect domain names along with their availability status.
simplerr - Advanced Go error handling, made simple
blockscan - a mini blockchain scanner
dgo - Efficient, error-free and high-level library for Dart <-> Go interops.
pcre - Pure-Go port of the PCRE2 regular expression engine.
snaky - snake game implementation using 2d array in Go
stringdedup - String deduplication package for Go
errors - Simple error handling primitives
