So this seems like an improvement, but I have to ask: wouldn't it be far better to just add a function to emit a warning and use that rather than all these print/++$warnings pairings? The current way seems repetitive and error-prone.
I also have to ask...

What does this signoff chain mean? If it really took three people to make this patch, then we need Co-developed-by tags to reflect that.
Thanks,
