MODERATORS
No. Duck types (including virtual subclasses) considered harmful; use real inheritance if your language doesn't provide anything strictly better.
It is incomparably convenient to be able to retroactively add "default implementations" to interface functions (consider for example how broken
readintois in Python). Some statically-typed languages let you do that without inheritance, but no dynamically-typed language can.This reads more as a rant against inheritance (without any explanation whatsoever) than a legitimate argument.
