[Discussion] Stricter implicit boolean coercions

Hello Internals, After the first discussion about this topic (https://externals.io/message/117608) I have created a preliminary implementation and an RFC for making implicit boolean type coercions more strict: https://wiki.php.net/rfc/stricter_implicit_boolean_coercions With this email I'm starting the two week discussion period. I welcome any feedback on it and hope to further iron out the implementation if needed. I mainly chose the route of introducing a deprecation notice because it is in line with other RFCs that have similar goals (like the Deprecate implicit non-integer-compatible float to int conversions RFC), and it is fairly non-intrusive. Best regards, Andreas
