[Pharo-dev] Collection groupedBy: and groups order

[Petr Fischer via Pharo-dev]

--- Begin Message ---

Hello, I found a useful method in the collection - groupedBy: - the result 
container is some PlugableDictionary (integer variant) and group order (keys) 
is not preserved.

Would not it be better to choose some other Dictionary variant, which preserve 
the order of groups (like in source Collection)?
