Hi,
I think you should je return whaterver is returned by the constructor.
And typeof {}==='object'
All lowercase
Your second call should be apply
And constructor isn't a property of instances, it is a property of the
prototype if i remember welll.
I'll post an implementation later if noone else does it because atm, i'm on
my mobile phone.
