  sub PutInPot { ... }

  Cook('lobster', 'water', \&PutInPot);


  Cook('lobster', 'water', sub { alert("pot $_[0]") });

I use this sort of programming on a daily basis, and it is extremely powerful.

Mark-Jason Dominus's amazing book Higher-Order Perl discusses this kind of
program in great detail and with great clarity.

I'll see if I can't find better free resources for functions-as-data in Perl.

See perldoc perlsub, too
