Dave Snead discovered problems with the following definitions: 


SetAttributes[CenterDot, Flat]

CenterDot[] := 1

CenterDot[a_] :=a


That caused a problem with exceeding  $IterationLimit  when he tried to

         CenterDot[x, y]



I brought up this problem years ago, and you can see how to get around it if
you goto

Scroll down and click on Flat

Then see the discussion of  (A problem with the Flat attribute and how to
solve it.)
