in reply to Subroutine chaining idiom requested

Here's mine, 34 chars for the task which did not specify a print requirement. 32 without the my for strict compliance. 27 if you use something shorter than $agenda like $a

tachyon

use strict; # a ref to a few subrefs to go, performing as secified # in that they take an array, do someting and return an array my $agenda = [ sub{my@in=@_;for(@in){$_=$_*2}@in;}, sub{my@in=@_;for(@in){$_=$_*2}@in;}, sub{my@in=@_;for(@in){$_=$_*2}@in;}, ]; # four my@a=(1,2,3);@a=&$_(@a)for@$agenda;print"@a";
