s) why it should use this approach". P.S. This is a not a direct problem of dynamism (ignore annotations even if they hard coded in source). Problem in that the Dart VM does not want rely on annotations (dynamism is better, determine everything at runtime or from magic lists).

>> This is a very misguided comment. >> Dart and JavaScript are both completely dynamically typed. V8 VM optimized for that (type dynamics). Dart VM has a lot problem with performance with this dynamics because Dart VM is a truly object-oriented VM and each value has its own type (including a user defined types and a lot types in the Dart SDK, also internal witt hidden implementation, and all their members). About "blacklists" and "whitelists". =================================== Method recognizer and [while/black]list VM: Improve performance of method recognizer and unify the it with the intrinsifier. https://codereview.chromium.org/468793004/ =================================== https://github.com/dart-lang/bleeding_edge/blob/master/dart/...

Most of them cannot be optimized due the other problems in architecture. P.S. All mentions about them are hardcoded (added in special lists by humans) because VM has a problems with performance because it cannot optimize code in some cases due the fact that the normal running mode in Dart VM is an (unchecked) production mode. Normal mode when (types system unsound) means that Dart VM cannot to guarantee that it has possibility correctly recognize a members (of internally implemented types) that are critical for performance.
