https://www.w3.org/Bugs/Public/show_bug.cgi?id=22808 --- Comment #16 from Boris Zbarsky <bzbarsky@mit.edu> --- So I just looked through the ES6 spec. The only other use of [[FunctionKind]] is to prevent subclassing a generator function. This use assumes that anything without a [[FunctionKind]] slot is not a generator, so works fine with Web IDL. What we _could_ consider is giving a [[FunctionKind]] slot to what the spec calls "Built-in Function objects" and checking it in http://people.mozilla.org/~jorendorff/es6-draft.html#sec-built-in-function-objects-call-thisargument-argumentslist (and modifying http://people.mozilla.org/~jorendorff/es6-draft.html#sec-built-in-function-objects-construct-argumentslist-newtarget to not check it, I guess). That's assuming we don't want the existence of a [[FunctionKind]] slot to imply the function is an "ECMASCript Language function". -- You are receiving this mail because: You are on the CC list for the bug.Received on Monday, 9 February 2015 17:50:03 UTC
