On: How not to check the validity of an email address

[prodigal_erik]

I've seen undergrads trying to write Ada:

  case x is
    when true => y;
    when others => z;
  end case;

You know, so the code doesn't stop compiling when someone comes along and adds values to the Boolean type.

Well, FileNotFound is a popular addition from what I hear.
