NAME

Attribute::Overload - Attribute that makes overloading easier

VERSION

version 1.100710

SYNOPSIS

  use Attribute::Overload;
  sub add : Overload(+) {
      # ...
  }

DESCRIPTION

The Overload attribute, when used on a subroutine, declares that subroutine as the handler in the current package for the operation(s) indicated by the attribute options. Thus it frees you from the implementation details of how to declare overloads and keeps the definitions where they belong, with the operation handlers.

For details of which operations can be overloaded and what the overloading function gets passed see the overload manpage.

Note that you can't overload constants this way, since this has to happen during BEGIN time, but attributes are only evaluated at CHECK time, at least as far as Attribute::Handlers is concerned.
