Re: [Pharo-users] Few newbie questoins about Pharo/Smalltalk capabilities

Well, one thing that might disappoint you in Pharo is UI libraries. You'd assume that system that has UI as integral part and relies on it would have excellent UI framework, but sadly that's not the case. Old framework - Morphic - is outdated; it's buggy, poorly documented, and its code is convolut

As class is just an object in Smalltalk, it would be reasonable to believe that #initialize message is always sent to class on creation. However, that's not true. It is only sent to classes that redefine #initialize. Also sending super initialize may lead to problems. None of these is mentioned i
