Common Uses
Coroutines are useful to implement the following:
- State machines within a single subroutine, where the state is determined by the current entry/exit point of the procedure; this can result in more readable code.
- Actor model of concurrency, for instance in video games. Each actor has its own procedures (this again logically separates the code), but they voluntarily give up control to central scheduler, which executes them sequentially (this is a form of cooperative multitasking).
- Generators, and these are useful for input/output and for generic traversal of data structures.

Famous quotes containing the word common:
“The work of the world is common as mud.
Botched, it smears the hands, crumbles to dust.
But the thing worth doing well done
has a shape that satisfies, clean and evident.
...
The pitcher cries for water to carry
and a person for work that is real.”
—Marge Piercy (b. 1936)
“Repentance keeps my heart impure;
But what am I that dare
Fancy that I can
Better conduct myself or have more
Sense than a common man?”
—William Butler Yeats (1865–1939)
