The caller should be able to call the methods in any order, it sounds like you have some horrible stateful code.

  You are wrong. Most interfaces in non-functional languages are stateful. Take the JDBC-interface: It's certainly not possible to call setTransactionIsolation(), executeQuery(), commit(), rollback() etc. in any order. Or list: add, remove, set, clear etc. It's still an interface.

    That is a stateful interface I'd consider bad. That's mostly because of the limitations of java though. Opening a transaction with a function argument and a commit/rollback return would have been much better.

      What about my list example?
