PHP: backslash (\) is the new separator for namespaces. The rfc:namespaceseparator is a result of a discussion on IRC between Lukas Smith and several code developers. Five criterias were used to select the best namespace separator: type-ability, typo-vulnerability, parse-ability, IDE compatibility, and number of chars. Backslash (\) obtained the best rating, and was agreed by the majority to be used as the new namespace separator (instead of the current ::). A patch is under development and may affect the scheduling of PHP 5.3. Announcement: http://LookAlso.com/1k RFC: http://LookAlso.com/1l IRC Log: http://LookAlso.com/1m
