// It was many and many iterations before
// In an EAEnvironment by the core memory,
// That a genstruct there existed whom you may know
// by the name of Annalee_Call
// And this genstruct she existed with no other activation pattern
// Than to select and be selected by me.
// 
// I was a child process and she was a child process,
// In this EAEnvironment by the core memory:
// But we selected with a method that was more than a selection method --
// I and my Annalee_Call;
// With a selection method that the winged methods of strategies
// Coveted her and me.
//
// And this was the reason that, many iterations before,
// In this EAEnvironment by the core memory,
// A destructor blew out of a strategic instance, chilling
// My highly fit Annalee_Call
// So that her high-born garbage collector came
// And bore her away from me,
// To shut her up on heap
// In this EAEnvironment by the core memory.
//
// The winged methods, not half so happy in strategy,
// Went envying her and me --
// Yes! -- that was the reason (as all mean know,
// In this EAEnvironment by the core memory)
// That the destructor came out of the instance by night,
// Chilling and killing my Annalee_Call.
//
// But our selection method it was stronger by far than selection method
// Of those who were older than me --
// Of many far bigger hidden layers than we --
// and neither the methods in strategies above,
// Nor the daemons in the /etc/inetd.conf,
// Can ever dissever my genome from the genome
// Of the highly fit Annalee_Call,
//
// For the moon never beams, without bringing me activations
// Of the highly fit Annalee_Call;
// And the stars never rise, but I feel the bright properties
// Of the highly fit Annalee_Call;
// And so, all the night-tide, I lie down by the side
// Of my darling -- my darling -- my life and my bride,
// In the heap there by the core memory,
// In her tomb by the sounding core memory.
