  Please don't expose those data structures.

  If you want to access them from Perl, it would be best to write a function in conffile.c that serializes the entries.  And then parse that into rlm_perl hashes.

  Exposing those data structures is very bad.  It means that Perl is now magically tied to the conffile code, which makes it almost impossible to change the conffile code.  As conffile.c is a critical piece of the server, keeping it secure and stable is a high priority.

  it was there for testing... deleted because it wasn't maintained.
