That's a fairly major performance enhancement.
Actually, they can't use it as much more than an optimization hint, per their own spec (see Sec 13.1 of the draft): "Static type annotations are used during static checking and when running programs in checked mode. They have no effect whatsoever in production mode. [...] A Dart implementation must provide a static checker that detects and reports exactly those situations this specification identifies as static warnings. However: • Running the static checker on a program P is not required for compiling and running P. • Running the static checker on a program P must not prevent successful compilation of P nor may it prevent the execution of P, regardless of whether any static warnings occur."
