So, at that point, then it sounds like we have a spec. Functionality of zpp, with an E_RECOVERABLE_ERROR where zpp would fail. Including any warnings or notices that zpp would have raised anyway (since `"1abc" would work when passed to an int, it should still work, notice intact). > Still, the fact that 100% consistency is not possible is not a strong > argument against at least *some* consistency and in favor of inventing new > rules. Sure. Makes sense. I'll work on a proof-of-concept this weekend. That is if nobody else wants to take it (or beats me to it) :-D. Thanks, Anthony
