The method Announcer>>#when:send:to: seems new in Pharo 3 (it does exist in Pharo 2, but inherited from Object, doing something else), while the older equivalent Announcer>>#on:send:to: does exist in Pharo 2, but is deprecated in Pharo 3. This poses a problem for x-platform code targeting both platforms.
Could Announcer>>#when:send:to: not be backported/added to Pharo 2 ? It is not a major problem, but it is annoying. Sven
