SigC(3pm)

SigC - Perl extension which wraps the libsigc++ signal library

  use SigC;
  $foo = sub {return shift;};
  $signal = new SigC::Signal();
  $connection = $signal->connect($foo);
  $signal->emit(1, 2); # calls $foo, returns a list containing 1
  disconnect $connection;
  $signal->emit(3, 4, 5);  # doesn't call $foo, returns an empty list

While this module can be used alone to provide signals, its primary use is to make it easier to write modules around C++ code that uses libsigc++. The signals provided by these other modules may have restrictions on the kinds of values they may be called with or return.
