I use C++ and Rust. Unfortunately, there are no persistent versions of the data structures I need available in any language (using dynamic FM-index as an example again). It is just interesting to think about “hybrid” systems where most of the code follows principles of data-oriented programming and some of the code deals with any unavoidable mutability.
