Example from the web:

grammar Parser {
    rule  TOP  { I <love> <lang> }
    token love { '♥' | love }
    token lang { < Raku Perl Rust Go Python Ruby > }
 }
 
 say Parser.parse: 'I ♥ Raku';
 # OUTPUT: ｢I ♥ Raku｣ love => ｢♥｣ lang => ｢Raku｣
 
 say Parser.parse: 'I love Perl';
 # OUTPUT: ｢I love Perl｣ love => ｢love｣ lang => ｢Perl｣
 start { sleep 1.5; print "hi" }
 await Supply.from-list(<A B C D E F>).throttle: 2, {
     sleep 0.5;
     .print
 }
 # OUTPUT: ABCDhiEF
 # No floating point noise:
 say 0.1 + 0.2 == 0.3;        # OUTPUT: True
 say (1/13 + 3/7 + 3/8).perl; # OUTPUT:  <641/728>
 # Infinite list of primes:
 my @primes = ^∞ .grep: *.is-prime;
 say "1001ˢᵗ prime is @primes[1000]";
 
 # Lazily read words from a file
 .say for '50TB.file.txt'.IO.words;

Example from hello-world:

say "Hello World";
