I'd like to point out that these aren't really closures... You're doing this one hundred percent, and there's nothing wrong. Closures, however, contain copies of lexical values that they were created beside, and those copies are kept independantly for each instance of the closure. For example: 
sub add {
    my $var = shift;
    sub { $var + $_[0] };
}

my $bar = add(3);
my $foo = add(5);

$\ = "\n";
print &$bar(6);
print &$foo(6);

This can be useful for initiallizing once, something that must be done repeatedly - in principal similar to objects.

Update: See more accurate closure definition in broquaint's reply.

Update: I apologize for all the inacuracies, please consider my node deprecated... ;-)
I may have been having too much sugar and not enough sleep at the time...
