Hey Kornel, First of all I want to tell you that the idea is really great!
But I'm wondering if it wasn't better to adopt something like https://github.com/nikic/PHP-Parser for this. I don't think it's PHPTal's job to optimize the AST, and since there's already an AST lib out there that has gained a lot of interest (I think it's used also by the latest wonders of https://github.com/ircmaxell/PHPPHP). Optimizers will come for sure since I'm wondering if I can use PHP-Parser also in doctrine/common :P Marco Pivetta http://twitter.com/Ocramius http://ocramius.github.com/ On 8 January 2013 23:43, Kornel Lesiński <kor...@geekhood.net> wrote: > > A while ago I thought about creating PHP *optimizer*.
