[Python-Dev] gc.garbage

I notice the gc docs say: The following variable is provided for read-only access: ^^^^^^^^^^^^^^^^ garbage A list of objects which the collector found to be unreachable ... This isn't clear to me. When I find finalizer cycles in gc.trash, I want to clean them up by breaking the cycles. Unless I remove the instances from gc.trash too, their appearance in that list keeps them alive despite that the cycles are broken. But "read-only access" seems to imply "don't mutate", and I don't believe that was intended. True? False?
