comments field are ignored in JSON.stringify

I'm using a module to parse apache configuration files into json

https://github.com/tellnes/node-apacheconf

it works just perfect . when I perform JSON.stringify() the resulted JSON object doesn't contain comments . output of console.log(config) :

I don't think you can use keys like that inside arrays.

For example, try changing:

 DefaultType: [ 'text/plain', comments: [ [] ] ],

to:

 DefaultType: { type: 'text/plain', comments: [ [] ] },

Objects contain keys with values: { key1: value1, key2: value2 }

Arrays contain comma separated values: [ value1, value2 ]

Objects can also contain values that are arrays of values: { key1: [ value1, value2 ] }

or multi-dimensional: { key1: [ value1, [ value2, value3 ] ] }

It looks like a problem with the structure of your config object. I recommend changing it to match my examples.
