"However, many C compilers use non-standard expression grammar where ?: is designated higher precedence than =, which parses that expression as e = ( ((a < d) ? (a++) : a) = d ), which then fails to compile due to semantic constraints: ?: is never lvalue and = requires a modifiable lvalue on the left. Note that this is different in C++, where the conditional operator has the same precedence as assignment." http://en.cppreference.com/w/c/language/operator_precedence "i = ++i + 1; // undefined behavior[in C] (well-defined in C++11)" http://en.cppreference.com/w/cpp/language/eval_order The ability to break a compiler's legitimate optimisations by "casting away constness and volatility" (IIRC that took several years of committee deliberation as to whether it was required or forbidden behaviour!) And of course, the amusing C++ FQA. All of which makes the simplicity of Forth seem appealing :)
