Create compliant JSON always

Try to come up with ways of removing the extended syntax and always create 
compliant Json.

Examples:

1) Instead of casts: (MyType) { a: 1, b: 2 }
   use type identifier: { __type: "MyType", a: 1, b: 2 }
   for lists: { __type: "MyList", items: [ 1, 2, 3 ] }
2) For references use nested syntax:
     { "$ref": "a/b/c" }

Any conventions should be configurable if possible.
Attempt to use any industry or widely adopted standards.  Review syntax for 
Jquery, MongoDB, Microsoft, etc.
