<p>
Flix makes it simple and easy to evaluate <i>pure</i> code in parallel.
</p>
<p>
For example, the code on the right shows a parallel implementation of
the <code>List.map</code> function using the <code>par</code> construct.
</p>
<p>
Internally, the <code>par</code> construct uses
light-weight <code>VirtualThread</code>s.

<p>
Flix supports <a

concurrency</a>.
</p>
<p>
For example, the code on the left shows the creation of a fresh
region named <code>rc</code> in which two threads are spawned.
</p>
<p>
Importantly, control-flow does not leave the region before <i>both</i> threads
have terminated. Hence the two threads cannot outlive the lifetime of their
enclosing region.
