There was a problem hiding this comment.
Do we need the this: void? It's not actually accurate because if a thisArg is passed, then this won't be void.
If someone really does want to pass thisArg, this: void would stop them, but if this: void is ommitted, they will correctly get an error in --noImplicitThis mode, and can work around it by explicitly annotating a this type for their callback.
declare function f(cb: (this: void) => void, thisArg?: any): void;
declare function g(cb: () => void, thisArg?: any): void;
// Can't get a correct type for `this`, even with explicit annotation
f(function(this: string) {
this.toLowerCase();
}, "");
// Works
g(function(this: string) {
this.toLowerCase();
}, "");There was a problem hiding this comment.
thanks. should be fixed now.

I missed some methods in #16223, also coalescing
Array.fromsignatures using generic defaults.
