=head1 NAME
overloading - perl pragma to lexically control overloading
=head1 SYNOPSIS
{
no overloading;
my $str = "$object"; # doesn't call stringification overload
}
# it's lexical, so this stringifies:
warn "$object";
# it can be enabled per op
no overloading qw("");
warn "$object";
# and also reenabled
use overloading;
=head1 DESCRIPTION
This pragma allows you to lexically disable or enable overloading.
=over 6
=item C<no overloading>
Disables overloading entirely in the current lexical scope.
=item C<no overloading @ops>
Disables only specific overloads in the current lexical scope.
=item C<use overloading>
Reenables overloading in the current lexical scope.
=item C<use overloading @ops>
Reenables overloading only for specific ops in the current lexical scope.
