Thank you @QWYNG! The best would be to have a discussion about this in the Elixir Core Mailing list. In particular, I would love to know if other languages provide this and under which name. |

Closing this for now until pending ML discussion. We can always reopen it later! |

To me this is one of these things that doesn't come up that often but when it does it'd be extremely convenient to have such function. I like Clojure's name for this: frequencies. user=> (frequencies [:a :b :b :c :c :c])
{:a 1, :b 2, :c 3}Looking forward to the discussion on the ML. |

Hi! Thank you for a great programing language.
This is a suggestion and a PR in one.
Add tally function like Rubys tally.

Let me know if there's anything to be clarified/updated.
Hope it makes sense!
