NAME
Attribute::Overload - Attribute that makes overloading easier
SYNOPSIS
use Attribute::Overload;
sub add : Overload(+) { ... }
DESCRIPTION
The `Overload' attribute, when used on a subroutine, declares that
subroutine as 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).
BUGS
None known so far. If you find any bugs or oddities, please do inform
the author.
