Sort of, you can actually get away with invoking a function and not assigning its result at all I think assigning the error to _ is only necassary when you have multiple return values(one of which is the error) and you are interested in at least one of them. e.g. returnsTwoValues() is legal x := returnsTwoValues() is not maps are also interesting because value := someMap[key] is valid and value, keyIsPresent := someMap[key] is also valid.
