proposal: errors/result:

[MikhailBatsin-code]

Add a "Result" structure for handling errors like in rust or make it built-in.

why?

Lots of people consider go-way error handling very annoying and inconvenient, so there must be something that will make error handling in go better.

Solution(for full implementation check out my repository)

make a Result struct:

type Result[T any] struct {
    // must be private
    ok T
    err error
}

Please note that you should fill https://github.com/golang/proposal/blob/master/go2-language-changes.md when proposing a language change.

I realise this is technically not a language change, but if you are trying to change many func signatures from (T, error) to errors.Result[T], that is a large and breaking change that will affect the vast majority of Go code out there today.
