How about just using beloved tables instead? Maybe even with function literal to prepare some stuff, if you need to. for _, s := []string { p0[a:b], p0[c:d], // ... } { _, err = fd.Write(s) if err != nil { return err } } As others already implied it could have been cleaner with exceptions, but I don't think this is that one case where exceptions are particularly important. There is no recursion yet or anything like that.
