I love OO - but C++s objects are so bad that most of the time I just end up using functions-where-the-struct-is-the-first-argument, C style. If I'm feeling particularly energetic I might use the PIMPL idiom. But naiive use of C++ objects is absolutely painful for me.

All language constructs can be broken down into simpler ones, at the end of the day. We might talk about how subroutines are just overrated assembler macros. C++ isn't very clean so the fact that these fancy schmancy objects are just structs + function pointers is very obvious. But when done cleanly, I'd argue that an object is more powerful than the sum of its parts.
