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
evaluate
CenterDot[x, y]

I brought up this problem years ago, and you can see how to get around it if
you goto
http://www.verbeia.com/mathematica/tips/Tricks.html
Scroll down and click on Flat
Then see the discussion of (A problem with the Flat attribute and how to
solve it.)
