Earlier this week I watched Alex Chan's Sans I/O programming talk. In the talk, Alex argues the importance of separating I/O and program logic, with reference to a situation where his team was unable to use already-available parsing libraries for BagIt data because said libraries depended on local access to a file. This talk resonated with me because it made me realise I tend to couple I/O and logic in my code without realising it. I'd highly recommend watching the talk in full, or at least reading Alex's accompanying summary on their blog.
