Two of the Google engineers behind Dart unveiled the search giant's new language at the opening of the Goto Conference  in Denmark on Monday.
The problem is the lack of tools and people relying on a variety of libraries.
At least one of the people mentioned by name in that email, though, has distanced himself  from the communication. Chrome Frame developer Alex Russell called it a draft that "doesn't reflect either the reality of what has happened in the meantime or even the decisions that were taken as a result".
"You can write a web application in Dart and have it compiled and run on any modern browser. The Dart VM is not currently integrated in Chrome but we plan to explore this option," Bak said.
Bak is reported to have listed "the bad parts of the web" Dart hopes to target: the development of large-scale applications, lack of static types, no support for libraries, weak tools' support, and poor startup performance.
