"Just as" is a bit ambitious above, isn't it? Just look at how buildings
are built, and build OO systems accordingly. I wonder why nobody :-)
ever realized it is so simple. It is also extremely convenient for the
sake of terseness to make statements without any sort of supporting
argument. It reminds me of the writing style of several OO-speak gurus.

Please describe how you would view an OO program that does calculations
using matrixes of complex numbers as if it were a physical system...

Continue writing in this style and you'll become a wealthy OO-speak guru
like Brady Gooch or Steve Mellor. ``A sucker is born every minute.''

Just as a curiosity: could you post the titles of the OO books from
which you have gleaned the above statements? I must confess that I have
some expectations as to what they can be...
