This was my initial idea. I do not know much about YAML, but at least
Perl YAML implementations see no difference between different ways of
specifying undefined/null in YAML. I tried both YAML and YAML::XS
modules, and both seemingly do the same:

perl -MYAML -MData::Dumper -we 'print Dumper Load($ARGV[0])' 'field: ~'
$VAR1 = {
          'field' => undef
        };

perl -MYAML -MData::Dumper -we 'print Dumper Load($ARGV[0])' 'field:'
$VAR1 = {
          'field' => undef
        };

perl -MYAML -MData::Dumper -we 'print Dumper Load($ARGV[0])' 'field: !!null'
$VAR1 = {
          'field' => undef
        };

Maybe I am doing something wrong, but currently I am under impression
that YAML does not have enough flavors of "unknown" to cater our needs.

Best,
Andrius
