Yes, I realized that. Otherwise I would use USE_HASH_SEED_EXPLICIT and just rebuild the whole PPM repository with 5.8.1 before we release the corresponding ActivePerl. Then people could enable it explicitly if they did a clean install.

OK. In that >case it would be a no-op, so just avoiding it is better anyway. Yes, thanks! Cheers, -Jan -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
