The new "constructor tearoffs" feature includes the ability to use the `new` keyword in a place where an identifier is expected, and that identifier could denote a constructor name. We handle this by replacing the `new` keyword token with an identifier token whose identifier string is `new` (this should ease the burden on the implementations, since they are already set up to handle constructor names that are identifiers). Since all such situations follow a `.`, and `new` was never previously allowed after a `.`, the parser treats `new` as an identifier in any situation where it could possibly refer to a constructor, regardless of whether the "constructor tearoffs" feature is enabled. (This should allow for easier error recovery in the situation where the user tries to use the feature with a language feature that does not support it). It is up to the client to report an error if the feature is disabled. In this CL, I've implemented logic for the analyzer to choose whether to report an error based on whether the feature is enabled. I've implemented logic for the CFE to report the error unconditionally.

Dart
A client-optimized language for fast apps on any platform
Dart is:
-
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
-
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
-
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
-
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
-
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
License & patents
Dart is free and open source.
