That would be an excellent idea. But I feel like an even broader community should be created. Like a generic book club, but for code bases! Could even have a small handful of different code bases on the go at a time. I'd love to get to know lemmy's, but also e.g. neovim, or even unciv :)
Maybe one day it could even start tackling Moby Dick!
I still use Ada daily for my personal projects after having used it at work. I find it compliments my thinking patterns well. My only gripe with it is that they ate too much of their own dog food at AdaCore and now it can be hard to install Ada and gprbuild (due to a circular dependency). Plus gprc stole libgpr and broke some stuff too.
