Append to this string the optionally specified `numChars` characters starting at the specified `position` in the `bsl::string_view` object, obtained from the specified `suffix`, or its tail starting at `position` if `numChars` exceeds the length of this tail. If `numChars` is not specified, `npos` is used. Return a reference providing modifiable access to this string. Throw `out_of_range` if `position > strView.length()`. Throw `length_error` if the length of the resulting string exceeds `max_size()`.
