Yes, that makes sense.... 1.

Finder is just an illustration of the problem, that finder class can have much more behavior in a real example, such as a DAO or a Repository would have, and blocks could't be used properly to deal with that. cheers, Vitor On Sat, Jun 10, 2017 at 8:59 AM, aryehof <pharo...@aryeh.sent.com> wrote: > In SmallTalk:- > > 1.
