I definitely didn't say that the documentation was very good, just
that the library is generally not that complicated.
The problem with your suggestion is that the "standard Erlang types"
are very ambiguous because there's no way to distinguish a list of
numbers and a string, and an empty proplist is indistinguishable from
an empty list. On top of that, if you were to support tuples as JSON
arrays then you would have another ambiguituy with the representation
of a proplist.
