My preferred idiom is essentially the command pattern:

    type Frob struct {
      SomeFlag bool
      AnotherArg string
    }

    func (args Frob) Do() FrobResult {
      // ...
    }

    // Later:

    res := Frob{SomeFlag: true}.Do()

This saves the stuttering of `Frob(FrobOptions{`, should have identical performance to that, with nicer syntax, and has a smooth upgrade path for all the sorts of things folks do with the command pattern (such as logging, dynamic dispatch, delayed execution, scripting, etc).
