Go has "defer", which is great. Perhaps it should have a similar "whenever" construct. val, err := foo() if err != nil return err vee, err := bar() if err != nil return err Would become: var err error whenever err != nil return err val, err := foo() vee, err := bar() Static analysis would insert the appropriate check any time err is assigned in the function. Aliasing might be a gotcha, but I'd bet that is a rare case and static escape analysis could maybe catch it and either error, or just insert extra checks.
