Something like [curry-this](http://nmotw.in/curry-this) would be nice to have, so we could do something like: ```js const add = ( (a, b, c) => a + b + c )::curry(); ``` On Mon, Oct 19, 2015 at 1:00 PM, Bob Myers wrote: > Of course, faster is always better, and native is

Lexical scope while extending prototype?

I do understand Arrow functions are like built-in functions in that both lack .prototype and any [[Construct]] internal method. But why does the scope refer to the global in case of : ``` String.prototype.repeat = (n) = Array(+n+1).join(this); ES6 .repeat(3); // will result in [object
