  Rust's Rayon could probably have a mode with additional heuristics, so it wouldn't multi-thread if it guessed the memory usage increase or overhead would be too much. Not really automatic, but for some iterator chains you can just slap an adapter on. Currently you have to think and benchmark, but for some scripting type applications the increased overhead of the heuristics might be justified, as long as it was a new mode.

  Reposting this answer as it’s relevant here too - we already do this - a modern superscalar CPU is essentially an engine for turning sequential code into 6-8 (or more!) simultaneous operations that are dispatched all at once. Downstream, some 4-8 (or more!) ops are retired at once, their operations complete. This is all in a single core.
