# ABSTRACT: lexically import functions from non-lexical exporters
use Exporter::Lexical 0.02 ();
use Module::Runtime 'require_module';
=head1 SYNOPSIS
package Foo;
use Moose;
use lexically 'Scalar::Util' => 'reftype';
=head1 DESCRIPTION
This pragma turns normal package-based exporter modules into lexical exporters.
This can be useful to ensure that your package namespace doesn't get polluted
(preventing the need for something like L<namespace::clean> entirely).

no strict 'refs';

};

my @exports = grep {
ref(\$stash->{$_}) ne 'GLOB' || defined(*{ $stash->{$_} }{CODE})

-exports => \@exports,
}, $scratchpad);
