[jinja2] 変数を二重展開したい

こんな感じの変数があるとして

{% set id = 1 %}
{% set user.1.name = 'hoge' %}

こうした時に、 id = 1 が入って、 user.1.name になって、 hoge が返ってくるのを期待しますがうまくいきません。

{{ user.id.name }}

=> 'user.id.name'

idが展開されていません。 idを展開させてあげたいのですが、どうしたらいいのでしょう :thinking:

{{ user.'{{ id }}'.name }}
=> 'user.'{{ id }}'name'

{{ 'user.' + id + 'name' }}
=> user.1.name(idは展開されるけど名前が展開されない)

{{ 'user.' ~ id ~ 'name' }}
=> user.1.name(idは展開されるけど名前が展開されない)

この辺は全部ダメでした。結論から言うと、これでできます。

{{ user[id].name }}
=> 'hoge'

無駄に悩んだのでメモ。
三重展開とかすることが今後あるかわからないですが、その時も同じ手法で可能なのかきになるので今度調べてみよう
