I'm lost there. Isn't CPython using reference counting (i.e updating the 
object's state at each reference creation/deletion, and deleting the 
objects as soon as they have no more references to them) ? It seemed to 
me that generational GC only applied to periodic GCs, like tracing 
garbage collectors. Or is CPython using a mix of both technologies (to 
prevent cycles for example) ?
