I’m wondering: Is it OK that PerformPromiseAll invokes `resolve()` via `C.resolve()` (versus `this.resolve()`) with `C` determined via the species pattern? Rationale: `resolve()` uses the species pattern, too (which is why `this.resolve()` works well). Therefore, the species pattern is used twice, which may lead to unexpected effects: You define the species of `this` to be X, but the species of X is Y. Then `Promise.all()` creates an array with instances of Y, not X. -- Dr. Axel Rauschmayer [email protected] rauschma.de
