piece of code currently understands it, such understanding is not guaranteed to hold a few years from now. Be mindful of our scale With a codebase of 100+ million lines and thou- sands of engineers, some mistakes at runtime. If each project places their code in a namespace, project1::Foo and project2::Foo are now distinct sym- bols that do not collide, and code within each project’s namespace can continue to refer program (not always appropriate) or using exceptions (which are for- bidden). • If the work fails, we now have an object whose initialization code failed, so it may be an unusual state requiring a bool IsValid()

Alternatively, there’s of the code. If you’re going to have to explain it at the next code review, you should comment it now. Complicated operations get a few lines of comments before the operations commence. Non-obvious ones reading the code knows Python (though not what you’re trying to do) better than you do. # BAD COMMENT: Now go through the b array and make sure whenever i occurs # the next element is i+1 Classes link￿ If

nearby lines as well, possibly triggering a cascading series of reformattings. That one-line change now has a “blast radius.” This can at worst result in pointless busywork, but at best it still corrupts really in camel case per se; it defies any convention, so this recommendation does not apply. 3. Now lowercase everything (including acronyms), then uppercase only the first character of: 15 • … each
