// If you use the eval function indirectly, by invoking it via a reference
// other than eval, as of ECMAScript 5 it works in the global scope rather than
// the local scope. This means, for instance, that function declarations create
// global functions, and that the code being evaluated doesn't have access to
// local variables within the scope where it's being called.
const globalEval = eval;

// A reference to the global object.
