The PHP internals mailing list is discussing the RFC for deprecations planned for PHP 8.6. Gina P. Banyard announced the RFC, noting each deprecation will be voted on individually and the RFC must be frozen by July 13th. Key discussion points include: a call for impact analyses on the proposals (with Osama Aldemeery sharing data showing the return-in-finally deprecation affects only 0.18% of top Composer packages); controversy over deprecating the _() alias for gettext() due to widespread use; debate over deprecating 'let' as an identifier; questions about CURLOPT_PROGRESSFUNCTION deprecation (which appears to be an editorial error with no dedicated RFC section); and concerns about deprecating ArrayIterator methods and by-reference return modifier changes via inheritance.
