Thanks a lot, Aristotle, for attempting to correct any possibly misleading meanings. Safe.pm and ops.pm both use Opcode.pm. Neither Safe.pm nor ops.pm use either other. As I said and as Artistotle echos here, ops.pm doesn't compartmentalize - it drops "permissions" completely. Of course, permissions are access to opcodes.

This is far afield of the original question, and I'm not here for the chatter. The original question was, does Safe.pm thwart attacks? My answer was simply that I do trust ops.pm to do just that - thwart attacks - and ops.pm is related to Safe.pm, and the original author should consider another direction entirely for what he is trying to do, dispite this validation.
