	Nope.  (D'oh!)

	Right.  In copying from my grammar to an e-mail message, I
	goofed.  That should read:

 		addExpr
 		    : e1:mulExpr
 		      (ao:addOp! e2:addExpr!
 		      	{
 			    ## = #([ADD_EXPR,"ADD_EXPR"], ao, e1, e2);
 			}
 		      )*
 		    ;

	However, the same problem still exists.  Help!
