Task in Verse

A task is an object used to represent the state of a currently-executing async function. Task objects are used to identify where an async function is suspended, and the values of local variables at that suspend point.

Tasks execute concurrently in a cooperatively multitasked environment.

A task can be durational, based on a lifespan of one or more updates before it completes.

Tasks can be sequential, overlapped, staggered, and so on, in any logical order.

The sequence and overlapping flow of tasks is specified through the use of structured or unstructured concurrency expressions.
