ES.Next & Beyond: Chapter-02: Expected Error doesn't occur

[danialmalik]

Yes, I already searched for this issue

Edition: 2nd

Book Title: ES.Next & Beyond

Chapter: 02: Syntax

Section Title: Block-scoped Functions

Problem: In the first code block, i.e.

{
    foo();                  // works!

    function foo() {
        // ..
    }
}

foo();  // ReferenceError

in the later call to foo, a ReferenceError is expected. But when I run the code using node, there is no error there.
