[MATRIX-SIG] Much ado about nothingness.

[Ted Horst]

Has anybody looked at the Missing type from DigiCool ?  It has the desired  
behavior for arithmetic operations, but doesn't work correctly for math or  
umath functions.  I have no idea how hard this would be to get working, or even  
if this is the proper approach, but somebody else is at least looking at the  
problem.  You can get it from http://www.digicool.com/releases/ExtensionClass/.
