Devel::Callsite - Get current callsite
use Devel::Callsite;
sub $site { return callsite() };
print $site->(), "\n"; # prints one number
print $site->(), "\n"; # prints a different number
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).
