TYPO3: You can use this hook to modify all links generated on the website. Well, all links except those few over there, which for some reason use a completely different class that does basically the same thing, and will even call your hook, but then ignore the result completely.

Me: Fuck you! I've spent almost a day trying to find the right hook, because they are all undocumented, have stupid names and every time I get close to a solution, some other part of your code decides to circumvent the hook.

Also me: After spending hours sifting through the depths of the TYPO3 core, I seriously wonder why it works at all. Spaghetti code, classes fetching properties directly instead of using the getters, loads of global variables... Wtf is wrong with that thing?

And people say WordPress is shitty code.
