Agree with the design part. For making code easy to understand, my point in case is Qt; it's beautiful lib (always has been). It's not just 'approach' (e.g OOP) or 'language' (C++, java) it's a lot about context. Functional langs (and feature, looking at you java) are getting into spotlight because the computation model has changed. Shared state is too expensive. Once there will be exponential growth in RAM in place, the OOP model (e.g. shared state) will come back. Side note: one can write shitty code code regardless of technology. No need for OOP for that.
