Subject: RFC question (Re: [PHP-DEV] [PATCH] Allow use($var..) statement ubiquitously)
From: moriyoshi@at.wakwak.com (Moriyoshi Koizumi)

I would like to keep this as a RFC page in wiki.php.net. Are there  
any conventions or rules that I should keep in mind? (or just-not- 
supposed-to-do-that-because-your-proposal-is-stupid-and-will-never-be- 
accepted?)
