Greetings to everyone. As you remember, i was working at some new collections for Pharo Smalltalk. Today i want to share some results with the community. There are three collections currently implemented: - MultiValueDictionary - a dictionary which holda a pairs of "Key -> (Val1. Val2 ..)" - CircularLinkedList - a linked list which have additional pointer from its tail to head - Btree (do not forget to set the degree by sending the "degree:" message before start working. Also removing keys doesn't work correctly in some cases) Comments, suggestions and critics are very appreciatied, because you are my target audience.Collections are availiable for download on my project page: SmalltalkHub |   | |   |   |   |   |   | | SmalltalkHubLoading.
