overloading - perl pragma to lexically control overloading
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;
DESCRIPTION
This pragma allows you to lexically disable or enable overloading.
"no overloading"
Disables overloading entirely in the current lexical scope.
"no overloading @ops"
Disables only specific overloads in the current lexical scope.
"use overloading"
Reenables overloading in the current lexical scope.
"use overloading @ops"
Reenables overloading only for specific ops in the current lexical scope.

Class::MOP::Method::Overload(3) User Contributed Perl Documentation Class::MOP::Method::Overload(3)NAME
Class::MOP::Method::Overload - Method Meta Object for methods which implement overloading
VERSION
version 2.1202
DESCRIPTION
This is a Class::MOP::Method subclass which represents methods that implement overloading.
METHODS
Class::MOP::Method::Overload->wrap($metamethod, %options)
This is the constructor. The options accepted are identical to the ones accepted by Class::MOP::Method, except that it also required an
"operator" parameter, which should be an operator as defined by the overload pragma.
$metamethod->operator
This returns the operator that was passed to new.
