Documentation != checking of contract. All assertions can be removed from code easily with simple script when bloc will be released (or another solution will be found). Assertions really slowdown everything. Until version 1.0 bloc will have assertion and duplication in documentation. Cheers, Alex

Indeed, this pane is meant to be read-only. We would have to work on it to make it accept code.

IMHO if we keep the asserts, we should at least remove the duplication of repeating them in the comments. This will be a maintenance headache with little to no value added. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Starting-to-add-class-comment-and-test-on-BlElements-… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

I do not blame you. I am offended by Pharo disavowing the Smalltalk name. I am offended when people state Pharo is not Smalltalk. I want to refute false assumptions about the name Smalltalk, such as the equating it with cobol. Instead of taking it personally why don't you address my points about older programming languages whose names (AFAICT) are not perceived negatively? I support this community and am excited to participate in it. I admire and respect your efforts, StÃ©phane, in developing, organizing and supporting this community. But that does not mean I will keep quiet about something I profoundly disagree with and think is wrong. And that thing is to deny Pharo is Smalltalk. And I do this not because I am a zealot, but because words meaning are important, because to understand each other we should call a spade a spade, and because I am grateful for and delighted by this thing called Smalltalk, and I will not support taking credit away from it. Ruby is inspired by Smalltalk.
