Hi Frank, Thanks for the reminder. I’ll wait a few days to see if there is any other input before trying to implement this. The main output is using Google Closure Library which uses goog.bind and may also write a named property for @export, so it would be good to make sure other’s can’t think of any compatibility issues with trying this scheme with GCL.
