Greetings ES Discuss! We (Joey Schorr and John Lenz, CCed) are some of the authors of the source map specification that is now implemented by WebKit and Firefox, as well as a number of compilers (Closure Compiler, GWT and soon CoffeeScript). Given that the specification is becoming a de-facto standard for mapping of code which is compiled to JS, we were curious if there was any interest in making it an actual standard under TC39. The current specification can be found here: https://docs.google.com/a/google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit, with a number of contributions from all the various parties involved.
Thanks!
