Mark J. Reed concluded:
So I prefer keeping a single construct, but perhaps the else-part
could be optional?
I hope not. The mandatory else-part is one of the most valuable features of
the ternary operator. It helps ensure that variables initialized with a
cascaded ternary actually do get initialized:
$action = $name eq 'Kirk' ?? 'fight'
!! $name eq 'Spock' ?? 'think'
!! $shirt eq 'red' ?? 'die'
!! 'stand';
The required-ness of the else-part makes cascaded ternaries a safer, more
robust choice than if-elsif-else chains in many cases.
