POE Architecture: Layers of Abstraction
POE, The Perl Object Environment can be thought of as a tiny modular operating system. One or more POE programs or instances can be run concurrently and are generally well suited for cooperative multitasking. The POE package consists of namespaces and abstractions that guide future development of POE in an open-ended CPAN-style convention.

Famous quotes containing the words poe, layers and/or abstraction:
“I was a child and she was a child,
In this kingdom by the sea;
But we loved with a love which was more than love --
I and my Annabel Lee.”
—Edgar Allan Poe (1809–1845)
“I think it’s the real world. The people we’re writing about in professional sports, they’re suffering and living and dying and loving and trying to make their way through life just as the brick layers and politicians are.”
—Walter Wellesley (Red)
“When truth is nothing but the truth, it’s unnatural, it’s an abstraction that resembles nothing in the real world. In nature there are always so many other irrelevant things mixed up with the essential truth. That’s why art moves you—precisely because it’s unadulterated with all the irrelevancies of real life.”
—Aldous Huxley (1894–1963)
