Yes, but it's a pain to iterate over Options of Vec because you need to check/flatten twice. I am aware gcc/ghc is not relevant to rust discussions but I am not sure if rustc performs these specific optimizations. I expect it does because they are trivial. Who knows. I am just some random dude on the internet and a lot of drugs.
