...or in Python with generators/iterators. Or in Lua with coroutines. Or in Rust with iterators... I guess most higher-ish languages at some point gain support/framework for something like this. But the point stands: there's something both simple and powerful with pipeline abstraction. I think of pipeline as a way of thought. Something that bridges the gap between "user" and "programmer". It's no wonder some of that "way of thinking" was implemented into programming languages (with obvious and non-obvious implications, not limited to memory requirements).
