The last one.  I know it's slightly strange to a C programmer, but to a JavaScript programmer, it's not *too* strange, where a['foo'] === a.foo.  The advantage here is that in a getdns wrapper that is treating the results as JSON, you could use an existing json-pointer implementation.  Also, you don't have to worry about specifying the BNF for the query syntax, thinking about the edge cases, and worrying about the security consequences quite as much.
