Just to be clear, I completely agree that Pharo should move forward without any limitations and restrictions. Its just that when I first read the history of smalltalk I came to conclusion that like lisp , smalltalk is a freeform language , meaning that standardization meant much less for it than in other languages. Since Alan Kay was deeply inspired from lisp ( according to his own saying) a language that can change its own syntax is kinda difficult to see its as a rigid language that should obey to a set of rules. I dont know if it was Ingalis or Alan Kay that said that they created smalltalk not for it to remain in the state it was but to be the basic of new languages. So all this talk about ANSI standard smalltalk, sounds kinda weird to me. Sure I can see the benefits of standardization but that part was never crucial to smalltalk or lisp since the days they were created. And frankly this part that I love the most about smalltalk and lisp. So for me Pharo is 100% smalltalk and smalltalks that try to standardize things less than 100% ;) So I certainly agree with your blog post spirit. About moose 4.8 great work guys, I am amazed how deep moose is , and the horde of tools you have created for pharo. I recently took a deep look at it and it certainly moves code visualisation forward. I will love to see more video tutorials that show the practical advantages to coders like me that are not used to such kind of tools.

Yes, it is. FWIW, this particular piece of code (let's say 400KLOC to be closer to the truth) manages close to EUR 25 Million on a yearly basis. The worst bit in the whole system is not PL/1, it is the JCL scripts (hate, hate). And, truth be told, PL/1 is much better than any COBOL crap, allows for pretty advanced data structures. The environment is a mainframe one (zOS/IMSTP/IMSDB) and the storage looks much like NoSQL style. It is not JSON like Mongo but very very similar in how one would organize the data. The code is framework based and it works very nicely. Nothing really new under the sun with all those fancy new things as the whole system is message based (in/out) with terminal rendering or web rendering. Very same arch as an API of today. Now, code done right is not language dependent. I know the orginal developer, now retired. Very good, very smart, delivered a lot of working software over the years for a stunning number of verticals. PL/1 was his #1 choice I'd say.
