Hi, I don't know if anybody is using SETT to migrate from VW's Store to a Tonel repository, but I'm trying to pull back to Pharo a few packages I moved to VW and continued to maintain there. I don't understand why SETT creates a commit on a "per pundle" (package/bundle) basis. What would be the

Hi, I'm trying to load a package from a Tonel repository[1] that was created using SETT[2]. The structure seems fine, but when I try to load a package, I'm getting the message saying that there is no version for the package in the current commit (which seems wrong at least to the naked eye).

The M:N relationship is pretty straightforward in pure OO design. You have anEpisode that references a collection with instances of Track. And each Track has a collection of episodes. Of course this could be elaborated even further, and have an object like TrackPlay sitting in between of

Yes, it is the same. Everything is passed by "reference" (*). And if you copy the collection you'll get two collections referencing the same object. E.g. | a c1 c2 | a := Object new. b := OrderedCollection with: a. b identityIncludes: a. "true" c := b copy. c identityIncludes: a. "true" (*)

I agree with that, but in some cases, like reading objects from an ORM, you would be creating lots of instances of objects that are going to be discarded right away. This would put no stress on GC since it would happen in the "new" space, but would consume more memory (although I never measured
