I had originally tried on Safari 4.0.4 on OSX but just tried on Chrome (win)
and FF and got the same results.
So what you have is fine, the type returned on calling Boolean.apply(null,
[Object(true)] ) is indeed boolean.
The issue is that the value returned is incorrect when the original val is
false.
So try x = Object(false) and then echo the value of y. I'm getting a return
value of boolean 'true' instead of boolean 'false'
