I wonder if an interface like that is good to make it easier to construct Request objects...

b := client.Batch{}
b.Use(MailCapability)
b.Add("Todo/get", jmap.GetArgs{AccountId: "id", Ids: []jmap.ID{...}}, b.NextCallID())

b.NthCallID(1) // returns CallID of first request, for use in references

cl := client.Client{...}
resp, err := cl.Send(b)
