As I said in my previous response, read this article: https://dlang.org/articles/d-array-article.html You clearly do not understand at all how strings work in D. Strings in D basically _are_ string_views where most strings have the actual memory buffer managed by the GC. If you do string sv = "some string"; then _zero_ heap allocations take place. - Jonathan M Davis
