The text is wrong. The order of steps in the normative part of the spec (Section 10.5, esp. step 6) makes clear that variable declarations are not taken into account (but parameters and function declarations are). I suggest filing a bug, if there isn't one already: https://bugs.ecmascript.org/describecomponents.cgi?product=ECMA-262 /Andreas
