//
// flags is a string of single-letter options: "i" case-insensitive, "m" multiline (^/$ per line),
// "s" dot-matches-newline, "x" extended (ignore whitespace), and "g" replace-all (regexReplace only).
// A non-participating capture group is nil. Subjects and results are binary-safe; the natives are
// inline (they run on the calling context's thread). Matching is interpreted (JIT is not built).
