I've seen CS papers that use mainstream programming languages directly, instead of pseudocode, so you can just copy/paste it. However, many CS papers aren't an easy lecture either, even if they talk about something really practical. I remember reading the paper on String B-trees, which is a data-structure for string search optimized for external storage (so you don't have to fit the whole index in RAM) and even if I understood all the concepts, the language was rather obtuse for no reason.
