 <p>This really makes your programming go faster. Think about compiling code
 for the following C/C++ expression: <code>(a|b)*((x+1)/(y+1))</code>. Assuming
 the values are on the stack in the order a, b, x, y, this could be
 expressed in stacker as: <code>1 + SWAP 1 + / ROT2 OR *</code>.

 <p>"Okay, big deal," you say?  It is a big deal. Here's why. Note that I didn't
 have to tell this function which kinds of Values are being passed in. They could be
 <code>Instruction</code>s, <code>Constant</code>s, <code>GlobalVariable</code>s, or
