# 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).
=cut
our $INDEX = 0;
sub import {
shift;
my ($package, @args) = @_;
my $index = $INDEX++;
my $scratchpad = "lexically::scratchpad_$index";
my $stash = do {
no strict 'refs';
\%{ $scratchpad . '::' }
};
require_module($package);
eval qq[package $scratchpad; '$package'->import(\@args)];
die if $@;
my @exports = grep {
ref(\$stash->{$_}) ne 'GLOB' || defined(*{ $stash->{$_} }{CODE})
} keys %$stash;
my $import = Exporter::Lexical::build_exporter({
-exports => \@exports,
}, $scratchpad);
$import->($package, @args);
delete $lexically::{"scratchpad_${index}::"};
}
