It is actually very easy to change mochijson2 module not to produce
{struct,...} for decode (it's what I do). Encoding works without it as well.
The only problem with encoding is when to interpret something as an array or
object. mochijson2 supports explicitly specifying {array,[...]} as well as
{struct,[..]}.
