    func cmpNimIdentifier[T: string | cstring](a, b: T): int

  Source Edit

    func find(s, sub: cstring; start: Natural = 0; last = 0): int {....raises: [],
        tags: [], forbids: [].}

  Searches for `sub` in `s` inside the range `start..last` (both ends included). If `last` is unspecified, it defaults to `s.high` (the last element).

  Searching is case-sensitive. If `sub` is not in `s`, -1 is returned. Otherwise the index returned is relative to `s[0]`, not `start`. Use `s[start..last].find` for a `start`-origin index.

    func find(s: cstring; sub: char; start: Natural = 0; last = 0): int {.
        ...raises: [], tags: [], forbids: [].}

  Searches for `sub` in `s` inside the range `start..last` (both ends included). If `last` is unspecified, it defaults to `s.high` (the last element).

  Searching is case-sensitive. If `sub` is not in `s`, -1 is returned. Otherwise the index returned is relative to `s[0]`, not `start`. Use `s[start..last].rfind` for a `start`-origin index.
