To be fair, others want to hang more hats on class syntax, including traits (separate proposal) and const/abstract modifiers. Then there are the guards and trademarking strawmen. Class syntax is like a lint brush for such features. If we add it, it will accrete more semantics (with unambiguous syntax, I hope) over time. This is just inevitable, in my view. It makes me want to resist classes and look at smaller and more direct fixes for the two known prototypal hazards. /be _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
