I think we've wasted a lot of time on this.

> Personally, I value my code compiling in the future over more explicit error handling. New errors will hit my catch-all branch, and I can special-case them later as I see fit. But it's a philosophy/values thing.

OR, you can just do `fn() MyError` then `if myError := fn(); !myError.OK()` opposite to just `fn() error`. I actually use this "trick" on many of my projects and they worked great.

I'm not really sure why Go defenders MUST praise Go's error handling as if it's flawless and thus all fault signals must be a `error`. As I pointed out few comments back, Go is clearly promoting binary error handling i.e. `if err != nil { return error }`, as doing branched out handling for specific error type is much harder (one example is the "nightmarish manual type discovery" mentioned above), so it's far from flawless. It's useful, sure, and people are using it, but it's not flawless.

BTW:

See? You already doing manual type discovery, they slipped the idea so naturally into your brain you don't even notice the struggle. But what if the number of types that you need to take care of keeps growing? Is it scalable?

You know what, maybe they should add Sum type for error handling. Hope it's not too late now since many people already camped on the idea that returning an interface then and casting it for error handling is the best idea ever.
