Some specially structured structs produce results that cannot be resolved

[peakedshout]

It's not clear to me why there is an extra "symbol", which causes the result to be unresolvable.

type T struct {
	Ts [][]T1
}

type T1 struct {
	A   string
	T2s *T2
}

type T2 struct {
	D string `json:"d"`
}

func main() {
	t := T{
		Ts: [][]T1{
			{
				{
					A:   "TTTT",
					T2s: &T2{D: "dwd"},
				},
			},
		},
	}
	bs, err := toml.Marshal(t)
	if err != nil {
		panic(err)
	}
	fmt.Println(string(bs)) //Ts = [[{A = "TTTT"T2s = {D = "dwd"}, }]]
}

Slightly simpler test case:

package main

import (
	"fmt"

	"github.com/BurntSushi/toml"
)

type (
	Top struct {
		T [][]T
	}
	T struct {
		A string
		B map[string]string
	}
)

func main() {
	bs, err := toml.Marshal(Top{
		T: [][]T{{{
			A: "TTTT",
			B: map[string]string{"a": "b"},
		}}},
	})
	fmt.Println(err)
	fmt.Println(string(bs))
}

% go run main.go
<nil>
T = [[{A = "1"B = {2 = "3"}, }]]
