Things to avoid
But this API doesn't yet have a corresponding call to release a saved object. Just don't do this, basically. Always keep your Nasal data in Nasal space. In FlightGear however, you may want to check out the gcSave/gcRelease methods of the FGNasalSys class:  // This mechanism is here to allow naRefs to be passed to // locations "outside" the interpreter. Normally, such a // reference would be garbage collected unexpectedly. By passing // it to gcSave and getting a key/handle, it can be cached in a // globals.__gcsave hash. Be sure to release it with gcRelease // when done. int gcSave(naRef r); void gcRelease(int key);
