Hi, sorry if this is tangentially related to the conversation, however I've
just got a simple question. How would you call eval() with the ThisBinding
inside the evaluated code being a custom item? In ES5 we'd do something
like the following:
(function () {
eval(foo);
}).call(bar);
Would this change significantly with the advent of arrow functions and hard
lexical binding or am I not getting my head around how these are supposed
to be applied?
