perhaps it is a speed question? using pharo4.0 (with polymath): a:=DhbVector new: 50 random: 20. b:=a copy asOrderedCollection . Smalltalk garbageCollect . [ b removeDuplicates]bench. "'47,004 per second'" b:=a copy asArray. Smalltalk garbageCollect . [ b asSet asArray ]bench.

And I do not see why removeDuplicates is less ugly than asSet asArray. Just that it is doing two passes.

I think that it would be nice to have removeDuplicates. Because sometimes you need to end up with ordered collection and then you need to do something like `obj asSet asArray` and it is ugly.

about repeat:

by stepharo

Hi I saw that we added repeat: into strings and I understand the intention. Now could we find another name? Because I do not desesperate to get someone working on a type inference for Pharo and it would be good to have avoid to polute simple methods a repeat:. In SDL we also have repeat: and it would be good to have another method name too. Stef
