   No bothersome semicolons to type
   mechanically at the end of each line
   No troublesome type declarations to
   keep in sync (especially in separate files)
   No unnecessary words just
   to keep the compiler happy
   No error-prone framework code

   Ruby is designed to make programmers happy
   It allows you to concentrate on the creative
   side of programming, with less stress

    I hate type annotations
    Аннотации типов — это костыль
    Если мы добавим типы в язык, то
    их сложно будет убрать из него в
    будущем, когда вывод типов будет
    полностью автоматическим
