Attribute::Overload
Attribute::Overload
Attribute::Overload - Attribute that makes overloading easier
use Attribute::Overload;
sub add : Overload(+) { ... }
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.
If you talk about this module in blogs, on del.icio.us or anywhere else,
please use the attributeoverload tag.
