I imagine that a similar question was asked about the virtual 
methods...
Hide that into a pre-compiled's library special field, for 
example.
The runtime would maintain a "private data description" 
information about each class, read from the module. Private 
variables would simply not be put into the class, but in run-time 
specific data.
