> We are looking for any kind of benchmark in pharo, we would like to include such benchmarks in a reporting system for Pharo. Excellent idea. I have plenty of benchmarks for the applications I develop, but none specific to Pharo. Do you have in mind a particular reporting system? I have written HealthReportProducer, a small class that helps me to write benchmarks.

In addition, I MAY want to instantiate Abstract classes. Sometime you are doing prototypes, or TDD, and you want to instantiate an object of an abstract class. Even if you have a subclassResponsability. I don't care. Maybe I am not testing that right now, nor showing that to my client. I think the correct way to detect your kind of problems is with Lint. If it is not already done, maybe it could be added.

Re: [Pharo-project] Instantiating an abstract class

Yes please don't add that. It is alreday pain enough to get complicated objects setup in the right oder with the #initialize always being called (ok it is easy to work around and in many cases it is just fine, but you need to be aware of it).

Re: [Pharo-project] Instantiating an abstract class

by Stanislav Paskalev

And it will also require modifying the Pharo by Example book that says that there's nothing wrong with instantiating abstract classes and that there is no *abstract* class marker in this sense, only abstract methods. So, why would try to convert Pharo to another language ? Stanislav Paskalev On Wed, Aug 11, 2010 at 3:43 PM, Alexandre Bergel <alexandre(a)bergel.eu> wrote: > Hi! > > Just wondering.
