[Pharo-project] OOP best practices

Hi Hernan, just wanted to get your opinion on the following method, that attempts to adhere to your "complete objects" pattern. ( ESUG 2010 TALK). PerformedExperiment>>experiment: anExperiment start: aTime stop: aStopTime participant: aParticipant tasks: aCollectionOfTasks | experiment | experiment := self new. experiment experiment: anExperiment start: aTime stop: aStopTime participant: aParticipant tasks: aCollectionOfTasks. ^ experiment In your experience, how does the pattern cope with large keyword selectors. Maybe this case is not that evident, although we should try to avoid having more than 4 instance variables anyway, i would like to get your opinion on this problem (?). Thanks, Fernando
