Also, several of the techniques, especially those I doubt would hold up or be worth it (effort-gain-wise) under “real world” work conditions (as mentioned above) made me reflect on my coding style, and why I do or don't do some things (both on topics presented int he course and related ones), which I don't do that often (needed the impetus) but is really useful, even if I come to the conclusion that my style already suits my needs well.
