> Comparing item from map to null (to see if given key has a value) gives wrong results.
> The example included results in:
> has mother
> has father
> has mother (using not)
> has father (using not)
> Whereas the right result should be (as is in 5.1):
> doesn't have mother
> has father
> doesn't have mother (using not)
> has father (using not)
> Since the value for for key "mother" is not defined.
