PHPTAL package name

I've been informed on #pear that PHPTAL package should be renamed to HTML_Template_PHPTAL. That category definitely suits the project, but as far as I'm aware, this also requires change of package name and class names. Just change of package name doesn't sound very bad, it'll only require existing pear users to uninstall old package first (right?), but change of class name prefix seems very disruptive to me. It would require changes not only all over PHPTAL codebase, but also in all existing PHPTAL-based projects/framework adapters and some 3rd party extensions. I could provide wrappers or dummy classes that inherit new ones under old names, but that would be messy and nearly double number of files that have to be loaded (startup performance is PHPTAL's weak point already, and I don't want PHPTAL to be perceived as bloated and high overhead). Also, without real namespaces class names that are already overly long (e.g. PHPTAL_Php_Attribute_TAL_Condition) would get even longer. Some of those classes are visible to users. I wouldn't mind renaming classes when migrating to PEAR2. With real namespaces these problems are minuscule. So my questions are: Is it possible to have "PHPTAL" package in HTML/Template category? or HTML_Template_PHPTAL package that uses only PHPTAL as class name prefix? Can renaming be deferred until PEAR2? -- regards, Kornel
