`this` and `that` are arrows which range over a stream of data; `=` is copy, and `++` moves the arrow along the stream.
This isn't a "clever one-liner" it is a clear and precise syntax for expressing the operation the machine actually performs.
while(copy(current(stream_a), current(stream_b)) and not end_of_stream(stream_a))
You might prefer the above, but then, that's every other major language. The beauty of C is that the above code has to compile to something like the C version. C just allows you to actually express it
