Hahahahaha, WRONG!!!!!! It's one historical error of many years of stupid engineers, developers, programmers and boss!!!!! "Hand-written recursive-descent parser" == LL(k) however, people does it as LL(1). The grammar of Pascal language can be LL(1), but the grammar of C, C++ and Objective-C together won't can be LL(1). However, they together can be LALR(1) (or impossible in worst-case) from Yacc/Bison. Writing Hand-written recursive-descent parser miss-cleans the source code and goes hardfully to maintain it!!! The best option is a clean grammar in Yacc/Bison!.
