この stack queue を使った実装 TreeNode の初期化が重複している感覚があります。
ポインターのポインターを使うとなくせますね。

container/listを使ったことがなかったので質問させてください
.(bstElement)と書いているということはqueueにはbstElement以外の型の要素も入り得るということですか？- queue[1:]でRemoveを、appendでPushBackを行えるのでキューとしてcontainer/listを使うメリットがあるのかよくわからなかったです。かといってデメリットも特に思いつきません。ここら辺のメリデリってどんな感じですか？Go 言語標準ライブラリの container/list を deque として使ってみたによるとdoubly-linked-listなのでdequeueとして使う分にはメリットがありそうです。
