-In version 5.2.1, the ''b'' prefix and the ''(binary)'' cast were [[http://php.net/manual/en/language.types.type-juggling.php|introduced for forward compatibility]] with the PHP-6 project. As it is known, that project never came to be. However, these are still accepted by the language scanner although ignored from then on. +In version 5.2.1, the ''b'' prefix and the ''(binary)'' cast were [[http://php.net/manual/en/language.types.type-juggling.php|introduced for forward compatibility]] with the PHP-6 project. However, that project never came to be and no one can tell if it will ever be the chosen approach in a possible future attempt to implement binary strings. Yet, these are still accepted by the language scanner although ignored from then on.

-This RFC aims at deprecating the prefix as it produces no effect on the string literal and the binary cast because it is the same as casting to string.+
  
 ===== Proposal ===== ===== Proposal =====
 +This RFC aims to deprecate the prefix as it produces no effect on the string literal and the binary cast because it is the same as casting to string.

 The proposed implementation consists in throwing a ''E_DEPRECATED'' during compilation when the prefix or the cast are used. At a later major version of PHP, the support for these should be removed. The proposed implementation consists in throwing a ''E_DEPRECATED'' during compilation when the prefix or the cast are used.
