Steve Fink once sayd on p5p really wise and funny things:
in reply to Object Orientation is:
Ok, so I didn't really mean that about information hiding. Dramatic
license. But it is one of the things that bothers me the most about OO
code. A "real OO programmer", when given the task of implementing a
heart, would take a real heart and coat a meter thick layer of plaster
around it, then drill holes down to the aorta and stick tubes in them.
He would tell you how great it is that you can replace the buried hear
with a vacuum cleaner or a rooster without changing anything else. Whe
you complain about the tubes sticking out of your chest and the
wheelbarrow you need to push your new heart around in, he'd quickly
point out that the wheelbarrow is really an advantage because you can
haul around all kinds of other great things at almost no added burden.
