I use `Enum.group_by([1, 1, 2, 3, 4, 4], &(&1))` to count the number of item apparence once for a while, so identity definately help on reveal the intension.
Talking about the length of code, Haskell name this function `id/0`, so maybe we can consider `Function.id/1` if it's not too misleading. Wondering if anyone working on this or it's still in discussion, if not I'm more then glad to send a PR either you guys like `Function.id/1` or `Function.identity/1` José Valim於 2019年8月2日星期五 UTC+8下午11時13分02秒寫道： > > Precisely.
