I'm using ES6 generators to implement a little async/await library and I'm quite pleased with the result so far but I'm lacking one API: a function to get stack information from a generator object. Ideally it would return the name of the current generator function, the filename and the line number where it last yielded.
If I had this API I 'd be able to provide a complete trace of the stack of await calls when an exception is caught. I raised the subject in the v8-users mailing list and Andy Wingo replied that this could be an interesting addition to the Reflect module and that I should post here. I've got another less important suggestion regarding syntax but I'll post separately. Bruno
