=head1 NAME
Test::Stream::Compare::Scalar - Representation of a Scalar Ref in deep
comparisons
=head1 DEPRECATED
B<This distribution is deprecated> in favor of L<Test2>, L<Test2::Suite>, and
L<Test2::Workflow>.
See L<Test::Stream::Manual::ToTest2> for a conversion guide.
=head1 DESCRIPTION
This is used in deep comparisons to represent a scalar reference.
=head1 SYNOPSIS
    my $sr = Test::Stream::Compare::Scalar->new(item => 'foo');
    is([\'foo'], $sr, "pass");
    is([\'bar'], $sr, "fail, different value");
    is(['foo'],  $sr, "fail, not a ref");
