// C cannot reuse `impl_cyclomatic_c_family!`: that macro hard-codes a
// `Catch` decision arm, and C has no exceptions (no `catch` token). The
// decision-kind set is otherwise the C-family one — `if`/`for`/`while`,
// `case`, the `?:` ternary, and the `&&`/`||` short-circuit operators,
// with `switch` adding only to the modified count (#284).
