* Seems kinda cool

* Makes $x == 5|6 look kinda cool

* $string ~~ /<first>/ & /<second>/ & /<third>/ # matches all three regexes. huh. kinda cool

* (5|6).foo maybe we can do that in cpu-parallel (it doesn't now)? That might be kinda cool

* sub is-prime($n where $n > 2) { $n % none(2..sqrt($n)) == 0 } # Logical O(1) prime test if only you had that quantum-coprocessor? That... would be kinda cool

* ... you might notice a pattern to the motivation for this feature :)
