Guix

This module allows using a variety of events without forcing module authors to pick a specific event loop, and without noticeable overhead. Currently supported event loops are EV, Event, Glib/Gtk2, Tk, Qt, Event::Lib, Irssi, IO::Async and POE (and thus also WxWidgets and Prima). It also comes with a very fast Pure Perl event loop that does not rely on XS.
