For the *return-in-finally deprecation*, I did run an impact analysis. I just kept it out of the RFC entry itself, partly to keep the entry short, partly because I'd already shared the core of it in my original pre-RFC message on this list ( https://externals.io/message/131393#131393 - which lists all 12 affected sites), and partly because I hadn't gotten around to reposting it in this thread yet. So here it is, for you and for anyone else following along... I compiled the ~5000 most-installed Composer packages with the patched build and collected every site that triggers the new deprecation. It shows up in 12 places across 9 packages, about 0.18%. Reading each one: - 3 are latent bugs the deprecation would catch, where the finally return discards an exception the try can throw - the other 9 either deliberately rely on the discard or are harmless The full write-up, with the per-site breakdown and the script to reproduce it, is here: https://github.com/aldemeery/php-rfcs/tree/master/deprecate-return-in-finally Thanks, Osama
