Problem in Symfony components I often see is readability in some places is really bad. This is being done for sake of performance, but I don't agree minor speed improvement always trumps readability. Often times this is done for too tiny performance improvements. Especially problematic are huge nested blocks with no comments. In my opinion your team members are doing job of zend compiler and this makes code hard to maintain, review, debug and contribute to. What's your take on this issue?
