Tx we will remove it. In pharo 70 we will have - a classParser with a class definition to handle all the terrible logic of importing - a fluid class definition - and it will help removing duplicated and old logic with a huge number of optional parameters ...

This one looks strange and seems indeed to be dead code. Maybe it was an attempt to make a specific class definition keyword for CompiledMethod / CompiledCode / CompiledBlock. Right now there is a specific case in the code somewhere to use the specific compiledCode layout for those 3 classes instead of the byte layout which is normally used for the keyword variableByteSubclass: that those 3 classes use. I am not sure immediateByteSubclass: makes sense though. I would rather have compiledCodeSubclass, variablePointerAndByteSubclass or something like that.

Re: [Pharo-dev] [ann] bloc & cairo+morphic

by Tudor Girba

Hi, It seems that my initial message generated a misunderstanding. My original blog post was meant to communicate two things: 1. That the known Bloc project has received a new feature that the community raised as a problem (i.e., host & backend). 2. Address the other concern that the community raised: how to sustain the Bloc development in terms of engineering effort. This is why we announced the financial support for the work of Alex that is valid from this point on. The post was certainly not intended to overlook the people that contributed to the overall project. I apologize if it looked like this. To clarify the historical perspective, we now added an explicit history page on the official project page: https://github.com/pharo-graphics/Bloc/blob/master/HISTORY.md I also changed the blog post to more clearly communicate the intent: http://www.humane-assessment.com/blog/bloc-flexible-backends-hosts/ I hope this addresses the concerns. I am really excited that Alain joined and that we can get even more traction around Bloc.
