Prior Art
Fortran has an intrinsic function index
(description) which does the same thing but has limited features.
PS: Some of the features proposed above may not be best to add to the stdlib at this moment, hence there is also a need to discuss the importance of these features. They are added in the issue to bring them into the discussion.
