\brief This is an auxiliary function used to simulate private declarations. Whenever we want to create a "private"
|
|
declaration, this module creates an internal "hidden" name that is not accessible to users.
|
|
In principle, users can access the internal names if they want by applying themselves the procedure used to create
|
|
the "hidden" names.
|
|
|
|
The optional \c base_hash can be used to influence the "hidden" name associated with \c n.
|
|
|
|
The mapping between \c n and the "hidden" name is saved in the .olean files.
