Hmmm... I've never read that, but to just construct one on my own: 
$agenda = [ sub { "Hello" }, sub { scalar reverse shift }, sub { chop 
+shift } ];
chain($agenda, [ ]);

### BEGIN GOLF MODE ###
sub chain($$) { my@x=@{+pop};foreach(@{+shift}){@x=$_->(@x)}@x }
### END GOLF MODE ###

Update: Fixed argument-modification error, thanks to tilly for pointing that out.
