кажется что оно вполне себе запоминает свой диспатч

как минимум

так что оно делает его довольно быстро и не каждый раз

ну или если это не так то там какой то ваще невидимый оверхед

так или иначе я считаю что идея интерфейсов крутая

интерфейсы/трейты

как хотите называйте

так мне вдруг стало интересно

Лол.

Неплохая статья действительно.

Во всяком случае не бестолковая.

" The venerable master Qc Na was walking with his student, Anton.  Hoping to
prompt the master into a discussion, Anton said "Master, I have heard that
objects are a very good thing - is this true?"  Qc Na looked pityingly at
his student and replied, "Foolish pupil - objects are merely a poor man's
closures."

 Chastised, Anton took his leave from his master and returned to his cell,
intent on studying closures.  He carefully read the entire "Lambda: The
Ultimate..." series of papers and its cousins, and implemented a small
Scheme interpreter with a closure-based object system.  He learned much, and
looked forward to informing his master of his progress.

 On his next walk with Qc Na, Anton attempted to impress his master by
saying "Master, I have diligently studied the matter, and now understand
that objects are truly a poor man's closures."  Qc Na responded by hitting
Anton with his stick, saying "When will you learn? Closures are a poor man's
object."  At that moment, Anton became enlightened."
