IEEE Spectrum, January 1990.  Cover topic: "Technology '90".  Under the
major heading "Systems software", there is an article called
"Object-oriented programming a hit" by Ted G. Lewis ("Expert Opinion").
Here's a passage from it:

	Perhaps the most powerful concept in object-oriented
	programming systems is inheritance.  Objects can be
	created by inheriting the properties of other objects,
	thus removing the need to write any code whatsoever!
	Suppose, for example, a program is to process complex
	numbers consisting of real and imaginary parts.  In a
	complex number, the real and imaginary parts behave like
	real numbers, so all of the operations (+, -, /, *,
	sqrt, sin, cos, etc.) can be inherited from the class of
	objects called REAL, instead of having to be written in
	code.  This has major impact on programmer productivity.

Sigh... maybe the April 1 issue was published early this year?
