To give some clarity to "whose concern is it", the idea of it being an ES concern is that this is a concern for all APIs that accept a callback. addEventListener is a simple example.
I think ES has already given an answer to this question: `Function.prototype.bind`. I'm not sure what the OP was hoping to accomplish that could not already be accomplished with bind. Any possible mechanism (e.g. syntactic sugar for a (thisArg, function) pair) would essentially duplicate what bind does under the hood. _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
