I think I heard about something like what you seem to want a bit ago called Announcements. Objects can "sign up" to be notified of a particular event. I dug up a wiki page about it.

Hope this helps,

Hi David,

short answer: anArray do: [:each| each message].

One of the things to learn about Smalltalk is it's rich collection protocol.

The fact that I use do: might hint that I should reread the protocol of collections, there maybe something more elegant :-))

Cheers

Herbert

As far as I can tell, messages have to be directed at a single recipient. Is this the case or, for example, is it possible to blast a message to every member of an Array at the same time?
