Seems to be an error in the Manual::Cookbook.
Under "Stringification" it says:
Employ the standard stringification technique by using the "overload"
module. Replace "foo" with the column/method of your choice.
use overload ’""’ => ’foo’, fallback => 1;
However, this results in an error of:
Can't resolve method "???" overloading """" in package "overload"
Changing the overload line to this (thanks Castaway!) works:
use overload '""' => sub { return $_[0]->foo; }, fallback => 1;
This is on Perl 5.8.8 (overload.pm $VERSION=1.04).
