# ABSTRACT: Compartmentalize Iterator::Flex::Method::Maker
use strict;
use warnings;
use experimental 'signatures';
our $VERSION = '0.18';
# Package::Variant based modules generate constructor functions
# dynamically when those modules are imported.  However, loading the
# module via require() then calling its import method must be done
# only once, otherwise Perl will emit multiply defined errors for the
# constructor functions.
# By layering the Package::Variant based module in an inner package
# and calling its import here, the constructor function, Maker(), is
# generated just once, as Iterator::Flex::Method::Maker, and is
# available to any caller by it's fully qualified name.
Iterator::Flex::Method::Maker->import;

    use Iterator::Flex::Utils qw( :default ITERATOR METHODS );
