Pardon if I've simply forgotten, but was it of intent to have modules tailored to the standard library? Such as teaching how the STL works, or using the thread library, or how to work with time via chrono? It looks like everything thus far is pretty specific to the core language pieces of c++. Was there a specific decision to not create modules for the library? Am I just not finding the discussion on that? Or is that work-to-be-done?
