thanks clement. I was looking for at: while occurrencesOf: was it. Now I introduced removeKey: ifAbsent: and keys because they are missing. S

Hello Everyone,
It also makes sense to me.
the message `addAll: aCollection`, is defined in **Collection** object. The behavior of addAll: is to add every object of the collection. So every dev who learn pharo will understand `addAll: aCollection` message, add all object of the collection aCollection. If you want to count a String just send an `add:` message to Bag object.
Finally the behavior of the Pharo Bag seems similar to Python Counter Object [1].
I don't understand why you found this behavior strange.
I hope it will help.

Because as you said, a Bag is for keeping occurrences. So, at: $a should return how many occurrences $a has

Hi
I wonder why I cannot get values of a entry using at:
| aBag | aBag := Bag new. aBag addAll: âaabbbacacccaâ. aBag at: $a
5
I have the impression that this is because Bag API never got the correct amount of love but may be Iâm wrong.
What is your opinion?
