I understand, but there is a little difference, you can find code out there
improving performance thanks to generics, I am not sure if we can get any
performance improvement by using "orelse return err".

Yeah I know, I like your proposal, it is just how they handle errors in the
V pr
func CopyFile(src, dst string) error {
r, err := os.Open(src)
if err != nil {
return fmt.Errorf("copy %s %s: %v", src, dst, err)

defer r.Close()
w, err := os.Create(dst)
if err != nil {
return fmt.Errorf("copy %s %s: %v", src, dst, err)

w.Close()

Not sure if you haven't tried them yet, but here:

I need some IPC too for a experiment, and was going to try them.

I tend to use errX (X is adapted according to context) for function scoped
errors, and err for block scoped errors

That way you don't shadow
You can use the vendor folder, just copy (or symlink, but you will need to
keep them updated) what you need there and will work.

Allowing this implicit conversion would be a bad thing? because it works
like generics without any new syntax.

Hello :) I think you need to give some samples of what you are doing

More than magic, it is a global convention. I guess it could be interpreted
as: when you access a directory, the web server will index its content and
will show you a list of links, if you want to override this behavior, you
could create your own index.
