Hi All! Im adding an announcer in my project, 'cause, in order to build a call graph, ill need to know about inferencer-stack movements. I was thinking, the meaning of it is to create an announcement object with it configuration for any push or pop of a stack that's similar to the runtime stack, these are a lots lots lots of objects proably with lesser optimization than BlockClosure. I was thinking in add extension methods that allow me something like
self announce: [ StackPush new ] ifAnyIsInteresetedIn: StackPush. Well, i have two questions: a) Am i right? b) subscriptions variable at SubscriptionRegistry is an OrderedCollection, but is commonly accessed to get the subscriptors related with some concrete type, why not a Dictionary? is not faster than an OrderCollection in the tipical case of use? Ok, it could complicate calls like 'remove: subscriptor' but, commonly if you have the subscriptor, you have the Announcement type. Maybe the common ammount of subscriptors in a announcer is too little? Thanks!
