I know this was just meant as a quick example for demonstration purposes, but you'd think you would want a return value from the subs, rather than a printed value. This allows a greater functionality of that method, such as placing the value in a scalar rather than printing it to the screen immediately. Meaning:
#!/usr/bin/perl -w
use strict;
my @objects = (
{
name => 'sheep',
speak => sub { "baaah" }
},
{
name => 'dog',
speak => sub { "woof" }
},
{
name => 'mouse',
speak => sub { "squeak (almost silently)" }
},
{
name => 'fish',
speak => sub { ".oO()" }
}
);
printf "a %s goes %s.\n", $_->{name}, $_->{speak}->()
for @objects;
__END__
a sheep goes baaah.
a dog goes woof.
a mouse goes squeak (almost silently).
a fish goes .oO().
(This is not even nitpicking or saying you did it a dumb way. I was just proud of my own observation on how to improve such a thing for wider use :P)
