Anecdote: 9 years ago I was at MSFT. Hands forced by long GC pauses, eventually many teams turned to hand-rolling their flavor of string_view in C#. It was literally xkcd.com/927 back then when you tried to interface with some other team's packages and each side has the same but different string_view classes. Glad to see that finally enjoying language and stdlib support.

(ReadOnly)Span<T> has been available for 8 years now, and even before that, in the legacy Framework, there were common readonly-ref string slicers.

You are assuming most devs know about this.

I do check the standard library for things that sound like they should be there as their common enough. My experience tells me this approach is not as common as you would expect, same for C# in msft, I don’t know how many people using framework knew about array segment.

ArraySegment for example.
