Hi,I think you are misunderstanding this issue. This is not high in the hierarchy. In the Moose image, every object can offer a menu of possible actions. Hence, it is an Object responsibility. Just like inspect is the object responsibility.Cheers,DoruOn Mon, Sep 29, 2014 at 4:34 PM, Johan Fabry <jfabry@dcc.uchile.cl> wrote:That makes me shiver as well ;-) In Pharo 3 this luckily is not the case.I just have the philosophy to try and avoid putting things high in the hierarchy to make things high up as simple as possible (but not simpler ;-) ). This even considering class extensions.In this case, we can put the responsibility for some Roassal thingy in a Roassal builder so I would put that feature (and the added complexity) there.
