I don’t think we should make it easier to shoot yourself in the foot by auto-binding methods (and thus creating new copies of the method for every instance of the class).

However, I think the main question is, will shipping the prefixed bind or prefixed call forms of the operator (`::a.b`, `::a.b()`), and/or the bind form of the operator (`a::b`), definitely preclude future extension with partial application, etc, or can those still be worked in somehow? If there's a way to include all four forms and leave open the future possibility of extension, I think, as Domenic points out, that we would see a lot of value from the bind and prefix forms as well.

Being able to do `foo.map(::this.bar)` is really great, and even `const extracted = ::foo.bar` is nothing to sneeze at. I know there's a thread on the issue tracker where a few vocal voices are complaining that they want partial application syntax and bikeshedding on various operator forms related to that, but I don't think that should discourage the excellent benefits that you're giving to everyone but those few. _______________________________________________ es-discuss mailing list es-discuss@mozilla.org<mailto:es-discuss@mozilla.org> https://mail.mozilla.org/listinfo/es-discuss
