Thanks for the answers. I also wonder why alias this does not the 
job.
Unfortunatelly even if it works, the _data is not the data I want 
to be used
as value for JSONValue. _data only contains keys, the values are 
stored
in another variable. JSONValue should contain both.

I hoped there is some operator overloading for implicit 
conversion of my
class to JSONValue.
I solved the issue with an toJSON method and a generic 
functionality which
checks for this method.

Kind regards
André
