Yes. Our experience was that implicitly short-circuiting on dereferencing undefined had benefits, but was more trouble than it was worth. I want the best of both worlds — an error when I don't expect undefined, and a way to explicitly permit short-circuiting on undefined. A syntax like Dmitry's proposal would make duck typing and lazy allocation patterns more succinct. — Sent from my device that I decline to endorse blindly. Nor do I request absolution for any typographical sins. _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
