   > h3 'Counter:';
   
   This code can also be written h3('Counter:');. Raku’s functional style means we can drop the parens (). So we have a function h3 with a Str argument.

Is this what's considered "functional" (as in functional programming) nowadays? Perl 5 (Raku's predecessor) had that for like twenty years now.
