The one on SqueakSource is pretty tight (portable):

   Installer new merge: #jsonParser

There are only about 10 implementations of #jsonWriteOn:, which could
be replaced with #jsonWriteOn:do:, taking one-arg block as the second
argument, or a visitor object if more flexibility is needed.

As I need to do pre/post processing each object written, it needs to be a SAX-DOM style callback parser. What would be my best option for JSon encoding in both Squeak and Pharo? If the sax is absent I will need to write it and I would like to do so in an existing encoder framework, such as Magma or Fuel. What would be best?
