FizzBuzz in very FP Perl 6 (inspired by lichtkind++'s talk)

fizzbuzz.p6

constant nums = 1, 2, 3 ... Inf;

sub replace($divisor, $word) {
    -> $n { $n %% $divisor ?? $word !! $n }
}

constant fizzbuzz = nums\
    .map(replace(3, "Fizz"))\
    .map(replace(5, "Buzz"))\
    .map(replace(15, "FizzBuzz"));

say fizzbuzz[^100];
