// Macro to be used for switch-case fallthrough (required for enabling
// -Wimplicit-fallthrough warning on Clang).
// This macro definition must not be included from public headers! Because
// clang's diagnostic checks if there's a macro expanding to
// [[clang::fallthrough]] defined, and if so it suggests the first macro
// expanding to it. So if this macro is included in a public header, clang may
// suggest it instead of the client's own macro, which can cause confusion.
