Package:          Scripting Engine problem
Bug Type:         Feature/Change Request
Bug description:intersection type incompatible with nullable props/returns

Description:
------------
This code yields "Default value for property of type X&Y may not be
null. Use the nullable type ?X&Y to allow null default value":

class Test {
    public X&Y $y = null;
}

Fine, let's add the suggested "?". But then I get "Parse error: syntax
error, unexpected token "&", expecting variable".

About returning null|intersection, should this be possible?

class Test {
    function foo(): ?X&Y
    {
        return null;
    }
}

Right now it yields a syntax error.
