Most of the time I end up writing if err != nil { return nil, err }. This seems better than a simple panic to me it allows the function to return, executing any deferred functions and doing any necessary cleanup. If I had any complaint it would be that go could offer some way to setup default handling that simply returns zero and error for any unhanded errors. I know the same thing can be done with try, catch finally but then you have the same problem of needing to know what errors may be returned so you can make sure an wrap that call in a try statement.
