There's a lot of things that you shouldn't do that people do every day.
To minimize risk, if you insist on having a '.' in your path, the most
important thing is to put it at the _end_ of your path.  This way, when
you type a command, it will hopefully find the real command first.  If
it's at the beginning of your path, and you're on a multi-user system,
you're just asking for trouble.
