Good practical advice... if you really start thinking about what is
going to happen when you take a digital square wave and use it as a
modulator on some other signal, probably by something evil and nonlinear
like multiplying the signals together, you can give yourself a headache
quite quickly!  

Just remember, one person's "aliasing artifacts all over the spectrum"
is another person's "gritty, trashy, beautiful dirt".
