Ah. That makes sense. I hadn't realized that squiggly brackets were lambdas.
Very cool. To prove that they are lambdas, I confirmed that the following
works:
$r1 > $r2 ?? {%matches{$p1}++}() !! {%matches{$p2}++}();
So, in this needlessly complex code, I basically create an anonymous
function and immediately execute it.
Cheers,
Daniel.
