I don't think one can reasonably justify adding more syntax (and eating another useful ASCII glyph) just to reduce some types of arrow functions by a few more characters; arrow functions are already incredibly compact. ~TJ _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
