missing ',' before newline in composite literal

Easy mistake to make! You'll need to use Values and Dict. Take a look at the Collections section in the readme:

Values

Values renders a comma separated list enclosed by curly braces. Use for slice or composite literals.

c := Index().String().Values(Lit("a"), Lit("b"))
fmt.Printf("%#v", c)
// Output:
// []string{"a", "b"}

Dict renders as key/value pairs. Use with Values for map or composite literals.

c := Map(String()).String().Values(Dict{
	Lit("a"):	Lit("b"),
	Lit("c"):	Lit("d"),
})
fmt.Printf("%#v", c)
// Output:
// map[string]string{
// 	"a": "b",
// 	"c": "d",
// }

c := Op("&").Id("Person").Values(Dict{
	Id("Age"):	Lit(1),
	Id("Name"):	Lit("a"),
})
fmt.Printf("%#v", c)
// Output:
// &Person{
// 	Age:  1,
// 	Name: "a",
// }

DictFunc executes a func(Dict) to generate the value.

c := Id("a").Op(":=").Map(String()).String().Values(DictFunc(func(d Dict) {
	d[Lit("a")] = Lit("b")
	d[Lit("c")] = Lit("d")
}))
fmt.Printf("%#v", c)
// Output:
// a := map[string]string{
// 	"a": "b",
// 	"c": "d",
// }

Note: the items are ordered by key when rendered to ensure repeatable code.

No problem. Let me know if you get stuck again - happy to help!

Values(DictFunc) cannot add comment of each field like following:

opt := &LoginOption {
Login : "MUST_EDIT_IT", // [TODO] This field is REQUIRED
Password : "MUST_EDIT_IT", // [TODO] This field is REQUIRED
}

Yes I've noticed this before but at the time couldn't find an elegant solution. I'll create a new issue to track this bug.
