Please consider that the the way practical development really happens[2]

I'm curious - do "practical" developers really feel like they have to rush out and update their tool chain whenever a new version of part of it comes out? Most of the projects I've worked on considered the language version as a fixed part of the technology stack, and almost never updated it. Even when using Python, which valued not breaking working code more than it's own zen. But changing anything that potentially affected all the code in a working project was pretty much never done, and always involved a lot of effort.

So the worst headache I got from language evolution was from trying to remember which set of features I had available for each project. No, that's second - the biggest one was from arguments about when we should adopt a new version. But breaking working code pretty much didn't happen.

+1, that's an excellent point well made. I have been in this situation and it was certainly frustrating *as a developer*, but it pretty much works for most businesses. Regards,
