You can implement those things, but then you'd be implementing them. Suppose you open a file (or a tcp socket, or a database transaction) while being connected over an http connection. How many LOC does it take to make sure that file is closed at the end of the http connection, through all possible error conditions? How confident are you that said code is correct? In elixir, it's 0 LOC.
Nice, finally a straight answer. To be clear, this is because Erlang forces you to think about such failures and also because the entire stack being designed for such fault tolerance, correct?
