"The idea of locking things down further, with final as the default, is insane" — @mjtsai http://mjtsai.com/blog/2015/12/21/swift-proposal-for-default-final/ … Couldn't agree more.

@mpweiher @mjtsai I disagree. Explicitly supporting subclassing makes sense to me. I understand not wanting it but the idea is *not* insane.

@griotspeak @mpweiher Making it explicit will inevitably prevent some workarounds from being possible. Can’t foresee where bugs will be.

@mjtsai @mpweiher that is unfortunate. Subclassing a type not meant to be subclasses is also unfortunate.

@griotspeak Subclassing a type not intended for it may be unfortunate, it may be necessary/desirable. Either way it is fixable. @mjtsai
