Does errcheck work well with gorm (https://gorm.io/) and it's way of returning errors? This is not an obscure library, it's quite widely used.

Does any language save you from explicitly screwing up error handling? Gorm is doing the Go equivalent of:

     class Query {
         class QueryResult {
             Exception error;
             Value result;
         }
         public QueryResult query() {
             try {
                 return doThing();
             } catch(Exception e){
                 return new QueryResult(error, null);
             }
         }
     }

Gorm is going out of its way to make error handling suck.

It's about the default error handling method being sane. In exception based languages, an unhandled error bubbles up until it reaches a handler, or it crashes the program with a stacktrace.

Compare to what golang does, it's somewhat easy to accidentally ignore or overwrite errors. This leads to silent corruption of state, much worse than crashing the program outright.

Gorm isn't using the default error handling.

That's one point in this discussion. The language allows error handling that way. Compared to a language with proper sum types or exceptions, where one would have to actively work against the language to end up with that mess.

I've seen a bunch of code that does the equivalent of the Java I posted above. Mostly when sending errors across the network.
