Once the wrapping is done, every wrapped node (multiplies expressions in your case) will have the "value" member. This can be used from within any primitive transform or context, if you are working on the expression after it is transformed by WrapExpression. So instead of eval(your_expr) you would do something like eval(WrapExpression()(your_expr)) and then you can assume value exists when it is needed.
