Yes, at ETH Zürich. I'm not a big fan of Eiffel, but pre- & postconditions + invariants are a great way to verify simple functions in isolation. Still needs integration and end-to-end tests to verify sufficient correctness in a complex distributed environment. On top of that, I really don't like strong OOP. It can be misused so easily. Multiple inheritance sounds good in theory, but just based on some Java inheritance code nightmares I've seen in my career so far, think 10s of layers of deep nesting done by misusing inheritance; multiple inheritance would massively overcomplicate many codebases. I'm very happy the industry seems to move into a pragmatic middle ground, where both lightweight OOP and lightweight FP have their uses.
