Perhaps it should be exposed through different operators. If someone uses packages (especially functions) provided externally, they might have a hard time coordinating what flavor is required by which part of what he is using. By analogy, imagine there was an environment variable that switched all grep's to egrep's. That would be a complete mess. -- Peter Eisentraut [EMAIL PROTECTED] ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
