"so" coerces to True or False. "say /c/" would output the match object "say
so /c/" says True. Depends on what you want to see.
" $x ?? $y !! $z" is a shortcut - "if $x use value of $y else use value of
$z" and ought to be used for the final value.
You may know it in perl5 as "$result = $x ? $y : $z"
Here I use it to avoid typing "if {} else {}" - a similar shortcut is
s/foo/bar/
|| say 'Failed!'
.say is a quick way of saying $_.say -a dot without any variable,
expression before it means "call this method on the topic variable which is
$_"
-y
