It will be a library on its own. I'm not really aware of the whole
story but basically it has been started some time ago and after having
been in standby mode during a while, it has restarted recently:

Indeed, a few glue code between program_options and property_tree
library would be a very neat solution, I completely agree with this
idea. Let's keep it in mind until property_tree is released. For the
storage problem, why not merely insert some dots into the variable
names without changing anything to the storage model itself: you would
query variables["object.subobject.field"] to access a nested field.
