Devel::Callsite is a better instance key than join $;,caller()[1,2]
=head1 NAME
Devel::Callsite - Get current callsite
=head1 SYNOPSIS
use Devel::Callsite;
sub $site { return callsite() };
print $site-(), \n; # prints one number
print $site-(), \n; # prints a different number
=head1 DESCRIPTION
This function returns the callsite (a number) one level up from where
it was called. See the tests for an example. It's useful for
functions that need to uniquely know where they were called, such as
Every::every() (see CPAN for that module).

Re: Devel::Callsite is a better instance key than join $;,caller()[1,2]
I plan to add the interpreter (Perl context, actually) address when I get a chance, Ben Morrow was kind enough to point out what I was missing. Then it will be more correct than the current version. Does anyone know if the context address is unique in mod_perl and with threads? If not, what can I do? Ted

Ted it seems like if it isn't, extending the instance key using the pid and tid would be best made the application developers problem. Suggesting an approach in the Devel::Callsite documentation by providing example code that produces an instance key that will be valid in forking and threading environments, would make more sense IMO than spoiling Devel::Callsite's focus. -- don't let the perfect become the enemy of the good -- some politician on CNN
