We can begin to discuss this p.r., but due to code freeze cannot merge it until the 5.43 development cycle starts. Hence, I've labelled this "defer-next-dev." |

I was looking over Perl#1674, where it was suggested that late INIT blocks behave like BEGIN, and Larry approved of that (25 years ago). But history has moved on, we have 25 years of code developed under the current behaviour of INIT and I suspect such a change is more likely to break existing code than fix anything. But looking at the code in S_process_special_blocks() we do still push the CV onto PL_initav, even though that CV will never be called. So don't push the CV if it's too late to call it.
