It certainly is not a generally applicable method for Dictionary (not all/most keys will not understand #beginsWith:), but for some senders, it might make sense, as it (I think) does for SystemDictionary. It would bother me less as a loose method packaged as part of something that "needs" it, but I would be inclined to deprecate/clean it if it is intended as part of the collection protocol. Clients/senders could always define something like #dictionary:hasKeyBeginningWith:.
One of the great things about Smalltalk is the ability to add methods to system classes. This is probably not the best use of that freedom. Has this been of _any_ help? :) Bill ________________________________ From: pharo-project-boun...@lists.gforge.inria.fr [mailto:pharo-project-boun...@lists.gforge.inria.fr] On Behalf Of David Goehrig Sent: Wednesday, July 08, 2009 12:33 PM To: Pharo-project@lists.gforge.inria.fr Subject: Re: [Pharo-project] doing bad things to Dictionaries.
