In a past version the RFC included an example of chaining. The current
version doesn't show an example, but does say it is possible. To be
clear:
$x = fn($a) => fn($b) => fn($c) => $a * $b * $c;
Is supported in the current implementation. It would similarly be
supported in the `|params| => expr` notation.
