Oh,
I hadn't considered you might mean that it is good to know that teher is a well supported JSON parser/writer available on VAST. If that is what you meant, you are absolutely right. It is a good thing Sven's NeoJSON components have been ported to VAST. It is such a nice and clean framework, well documented and supported by its developer. But he only supports the original version for Pharo.
And it is a good thing that Instantiations takes the lead on porting and maintaining the port on VAST.
We do, unfortunatly, not (yet?) have a vital open source community on VAST. I hope Tonel and the VAST Community Hub will help change that culture.
