I think that's a very interesting question, thanks for bringing it up. I
think a good approach here would be the same one used for function argument
typehints, i.e. allow NULL when NULL is specified as the default value. So
`public DateTime $date;` would not allow an explicit NULL assignment,
whereas `public DateTime $date = NULL;` would.
