Note: These requirements are a willful violation of the JavaScript
specification current at the time of writing (ECMAScript edition ---> 3 <---).
The JavaScript specification requires that the ToBoolean() operator convert all
objects to the true value, and does not have provisions for objects acting as
if they were undefined for the purposes of certain operators. This violation is
motivated by a desire for compatibility with two classes of legacy content: one
that uses the presence of document.all as a way to detect legacy user agents,
and one that only supports those legacy user agents and uses the document.all
object without testing for its presence first. [ECMA262]
