Ruby has a very primitive conservative GC -- it just scans the stack 
looking for pointers. If you are a time traveler from the 1950s then 
Ruby's GC might be an interesting study.

In any case it would be easy to fool Ruby's GC, if that's what you wish: 
allocate a pointer and hide data behind the pointer. The GC won't see 
pointers which aren't on the stack. You can manage that GC-concealed 
data however you like.
