loves abusing C++, assembler, C++0X, C and C99 features all in the same code, all in moderation.
goto abuse, exception abuse in normal code, variable length arrays, pointers to virtual functions, variadic macros, variadic templates, SFINAE, decltype, CRTP, coroutines, and all kind of hacks. I've yet to use Objective C in C++ code.
