The answer
No. Arrow functions have lexical this. call (used inside the polyfill) cannot change an arrow's this. This is the same behavior as the native bind.

Function.prototype.myBind = function(context, ...presetArgs) { const fn = this; return function(...laterArgs) { return fn.call(context, ...presetArgs, ...laterArgs); }; }.
Check this instanceof boundFn. If true, return new fn(...presetArgs, ...laterArgs). Otherwise, return fn.call(context, ...presetArgs, ...laterArgs).
Use rest parameters: myBind = function(context, ...presetArgs). Spread them in the returned function: fn.call(context, ...presetArgs, ...laterArgs). This merges preset and later arguments.
