Loops depend on the POE kernel loading them, you typically can't load
them independently of POE::Kernel.

You can get POE::Kernel to load a specific loop either by loading the
module they depend on:

  use Event;
  use POE; # loads POE::Kernel, which loads POE::Loop::Event

or by supplying a loop option to POE::Kernel:

  use POE::Kernel { loop => 'Event' };

  # 1.001 or later
  use POE::Kernel { loop => 'POE::XS::Loop::Poll' };

See "Using POE with Other Event Loops" in perldoc POE::Kernel.

Though that says they can be loaded independently, which typically
doesn't work, since they rely upon trace constants created by
POE::Kernel.
