I'd tend to agree. Every time I do any functional programming (which is rare), it leaves me with a 'better way to do this' feeling and a different view on things when I go back to writing a regular OOP language. On the other hand, I've worked with a lot of C++ programmers, that tend to be a bit smarter than the Java/C# programmers I've worked with. But, and it's a big but, some C++ programmers I've worked with really do have the Dunning Kruger effect. They write what they think is "smart code", but it's really horrifically complex code, that others have mentioned here as too complex for the next guy to easily debug. "If I had more time I'd have written less". (disclaimer, I clearly suffer from DK based on what I've just written...)
