> we might start to name and structure our data, functions, types too specifically for that domain. I once worked on a Perl script that had to send an email to "Harry". (Name changed to protect the innocent). I stored Harry's email address in a variable called "$HARRY". Later on a second person (with a different name) wanted to get the emails as well. No problem, just turn the scalar into an array, "@HARRIES". I thought it was very funny but nobody else did.
