LuaD: creating a flexible data filter system

[yawniek via Digitalmars-d-learn]

many thanks for the valuable insights.
so far i made a simple prototype with LuaD and classes, works 
nicely for when my niput

what so far is not 100% clear is if there is a way to have a 
parsed
msgpack or json documents being exposed in my lua code in a way 
so it behaves
like a lua object.
Ideally in a RW fashion so that changed then again can be 
processed by D code.
