in reply to How To: Make An Iterator

Hardly original but my own fibonacci number generator.

use strict; use warnings; $| = 1; sub infinite_fib { my ($last,$curr) = @_; return sub { my $temp = $last + $curr; $last = $curr; $curr = $temp; return $curr; }; } my $next_fib = infinite_fib( 1,0 ); print $next_fib->(), "\n" for(1..10);

Kinda fun just because it reaches infinity in a pretty big hurry if you let it run.
