Another way to do it. Put your code references in a hash, otherwise known as a dispatch table:

# Pick a more descriptive name for this hash, depending on your need
my %subroutines = (
  test         => \&test,
  another_test => \&another_test,
  third_test   => \&third_test,
);

for (qw(test another_test third_test)) {
  $subroutines{$_}->();
}

This lets you define exactly which routines you can call using this method, rather than opening up everything and anything in the main namespace.
