Subject: Re: [PHP-DEV] PHP 5.4 - Meta attribute (aka. Annotations) support discussion
From: guilhermeblanco@gmail.com ("guilhermeblanco@gmail.com")

Hi Larry,

For existent project examples and usage, here are 2 links of the
upcoming versions of Doctrine 2 and Symfony 2:

http://www.doctrine-project.org/projects/orm/2.0/docs/reference/basic-mappi=
ng/en#introduction-to-docblock-annotations
http://docs.symfony-reloaded.org/guides/validator.html

Please understand that Roman, Benjamin, Jonathan and I wrote this
Annotation parser for Doctrine, which was reused by Bernhard on
Symfony.
So I have clean understanding of the issue we have on hands and every
single point that it is required to address. That's why I wrote the
RFC.

Yesterday night a couple of people joined on #php.pecl and discussed a
possible new implementation.
I'll write what was discussed and probably some sample code.

Cheers,
