Because you're still doing the same thing -- using a string as the name of a function.

Here's the hash of subroutine references: 

my %actions = (
    this => \&this,
    that => \&that,
    foo => \&foo,
    bar => \&bar,
    zzz => \&sleepytime,
);

# ooh, tricky

foreach (@user_actions) {
    if (defined(my $sub_ref = $actions{$_})) {
        $sub_ref->();
    }
}
