Review comment:
Good that you ask, would you say my approach is more, or less readable?
I prefer the CRTP pattern. But it needs some changes to suit your needs (it
needs to use non-statics, since it needs to store the pattern/table). If you
prefer my approach I can refactor your code when I start on `startswith` or the
regex version of your kernel.
