you already have doc-block. nothing should be done in PHP core, but you have to parse it yourself.
The goal of annotations is to provide standard and powerful way.
On the other hand standard PHP expression syntax may be not enough for all cases.

 Agreed on that. I just thought it could be wise parse natively what is already out there. Anyways adapt our DocBlock annotation parsers to parse both (native PHP annotations and docblocks) shouldn't be that hard either.
As far as I see annotations are supposed to be accessed through reflections right? Or will it do something automatically as in Python?

Cheers,



Thanks. Dmitry.

Why not doc-block annotations? So it can be parse/understand that is
already there (Doctrine annotations for instance).
