there is a method like uniq in bash for collections in squeak?
to remove all duplications in the collection and get a collection with one of each distinct obj.
For example:
before: #('cat', 'cat', 'dog', 'cat')
after: (uniq) #('cat', 'dog')
There exist quite a few ways of doing the same in subtly different ways, depending on your needs. The more popular ones I can think of are:
aCollection asSet creates a new Set with all the elements of the collection, and sets by definition have only one instance of each element.
aCollection removeDuplicates removes the duplicates from the original collection itself. This only works if the collection is not of a fixed size (i.e. it doesn't work on arrays).
