Could you explain how the range of syntax you suggest (regarding annotations) is currently blocked? I'm not challenging your claim; I *personally* don't know and am interested. While certainly not supported natively, comment-based "annotations" can be implemented in user-land and processed via reflection (See doctrine-annotations[1]). There has also been previous work and discussion in the annotation space [2][3][4][5]. Based on my light reading, I couldn't find any objections to annotations with side-effects, but I could see that as an argument. However, I'm more curious what your perspective is. Personally, I really like the idea of being able to declare "side-effect free" as a feature. I don't know if I prefer the idea of a phph file, distinguished by extension (so I'm glad you mention alternatives such as declare). That said, I think that's mostly from shock and not wanting to ever go back to a world that included *.php4, *.php5, *.phtml, etc. :) Hope all is well, 1: https://www.doctrine-project.org/projects/doctrine-annotations/en/latest/index.html 2: https://wiki.php.net/rfc/annotations 3: https://externals.io/message/82813 4: https://externals.io/message/64895 5: https://externals.io/message/64722 -- Dustin Wheeler | Software Developer NC State University mdwheele@ncsu.edu "If you don't know where you're going, it's easy to iteratively not get there."
