null loaded as string #13

Closed achalddave closed 7 years ago

It seems null is parsed as a string in lyaml instead of as a 'nil' type, unless I'm missing something. Here's an example showing the issue, and a comparison with what Python does.

Thanks for the report; I can't believe I missed that every time I read the spec docs!

In order to be compliant with the spec, which requires support of null keys into maps, we can't map yaml null directly onto Lua nil, but with this commit we do at least get lyaml.null objects.
