package My::Pkg;
use IdolType;

# `values`: defines a method for getting all values
IdolType->values; #=> [ bless({ id => 1, type => 'cute' }, 'IdolType'), ... ]

# `indexer`: defines indexer methods to package
my $cu = IdolType->by_id(1); #=> bless({ id => 1, type => 'cute' }, 'IdolType')

# `getter`: defines getter methods to instance
$cu->id;   #=> 1
$cu->type; #=> 'cute'

# `local`: makes a guard object for overriding its data lexically
