Things get more complicated if you need to pass a handle to a C/C++ object into a Nasal script. There, you need to use a wrapped handle type called a ghost ("Garbage-collectable Handle to an OutSide Thing"), which has a callback that you need to implement to deal with what happens when the Nasal interpreter garbage collects your object. | Things get more complicated if you need to pass a handle to a C/C++ object into a Nasal script.
