`?lastindex` shows no message on strings [`lastindex(str)`](https://docs.julialang.org/en/v1/manual/strings/index.html) gives the maximal (byte) index that can be used to index into `str` . A link to [`lastindex(str)`](https://docs.julialang.org/en/v1/base/collections/#Base.lastindex) also shows nothing related to strings. ---
