      @mraleph @jorendorff @sulnedinfind Is this out of date then? https://www.dartlang.org/articles/why-dart-types/#optimism-on-down-assignments …

      @pcwalton it's to remove need in explicit casting. whole language is dynamically typed anyways.

      @mraleph That makes no sense to me. If you have types you should have casts…

      @pcwalton once again: you try to perceive Dart as a statically typed language, which it is not. It's like Smalltalk not like Java.

      @mraleph That isn't an excuse to have the types not mean what they say.

      @pcwalton that's why I say that perception shift is required, otherwise your expectations are off.

      @mraleph I would rather have the types be entirely dynamic with a static semantics that weak. :(

      @pcwalton I am not sure what you mean by entirely dynamic. Expando objects like in JS? Well Dart should have mirror builders one day.

      @mraleph I mean don't ship a static analyzer at all. It barely seems worth it.

      @pcwalton I don't pay much attention to what analyzer says with my code, but it's good to have it on the side as a linter.

      @mraleph Feels like a point on the curve where you don't gain much for your time spent writing down types. But we'll just have to disagree.

          @pcwalton that's why official style guide recommends only typing API and not typing local variables :)
