And it has its limits, too. If you're walking a dog on a leash, you
don't send a message to the leash to send a message to the dog to
walk. You talk directly to the dog. Like most programming principles,
it's something to read, to grok, and then to think about. I have yet
to find any rule which, if slavishly followed, will not lead to bad
code _somewhere_.
