Baroque?  I think you meant to say "Inexperienced programmers, minds
corrupted by the bizarre and perverse nature of C++, ignorant of the
fact that a C string is an array, find a time-honoured C trick from
days when life was simple and compilers non-optimising, confusing.
Clang, catering to these users and written by mad C++ programmers,
warns about perfectly good code."

OK.
