If this map is for beginners that need a framework we should wait to have a usable version with documentation. I think Bloc and Brick are not finish yet (I think) and reef lack documentation/tutorial. If a beginner see it on the map and test it he will have a bad first impression. And first impression count. This project should be on a waiting list the time there are stable and documented I think.

Re: [Pharo-users] #collect:as:Dictionary

by Peter UhnÃ¡k

What is the practical value of creating a dictionary from non-association objects? That seems to me like the programmer made a mistake and forgot something. But maybe you do it regularly, I can only speak for myself. However consider also this: #(a b c) collect: [ :each | each -> each first asciiValue ] as: Dictionary. "a Dictionary(1->#a->97 2->#b->98 3->#c->99 )" (#(a b c) collect: [ :each | each -> each first asciiValue ]) as: Dictionary.

Well, given FT, then Spec will change to use it. You don't want to keep two widly different implementations of the same widget. Now, there was talk of a FT-based tree widget, and, IMO, this is the way to go. Thierry > Peter

The first just collects each entry and builds an association with the index, and the second expects a list of assocations. They have different behaviors if the list does not contains (or does not only contains) associations: { $a -> 1 . $b -> 2. 'not_an_association' } collect:#yourself as:Dictionary. "works - I would not expect an error" { $a -> 1 . $b -> 2. 'not_an_association' } asDictionary "throws an error - as I would expect it "
