Hi Dragan, the whole problem comes from the thought of
needing to serialize any other type of objects different of
data transfer objects ( DTOs in VFP = empty-based objects )
Although is possible to serialize forms for example,
it's out of the scope for some of the reasons you expose.
Json will find his way in VFP now that SQL server supports it
( thanks to a fellow-countryman of you Jovan Popovic !)
