Right, the complication is that it isn't a *complete* delegation to CORE::GLOBAL::require. >That's the discrepancy I was trying to describe. We really have quite a >collection of different behaviours here with regard to CORE::GLOBAL. Yes, and we must maintain all, or at least most, of those oddities. We certainly can't start requiring CORE::GLOBAL::require overrides to supply their own parser magic. The core-supplied CORE::require and CORE::DEFAULT::require, however, must both have the parser magic built in. >(In all those cases where I have talked about bypassing the call checker >of an override, it is not actually bypassed, resulting in very strange >bugs, such as "too many arguments" and "not enough arguments" errors >from the same functional call.) This behaviour is up for negotiation. I think it makes most sense that the override's check-time magic *does* apply to a call generated through the override mechanism. The override function should have the opportunity to inline itself. -zefram
