Having tried that solution (the first patch), I found it to be more complex in implementation, interface, and documentation. I prefer the explicit declarations with no subtle behavior. > Even when we have %import we will > still be able to distinguish them. I can't comment there because I don't know how %import will behave. However, the old solution is restrictive in another way. It requires you to have a %union in order to separate pre's from post's even when you don't want a %union. The union is just one of several Bison-generated definitions that might need to divide user code in the header file. Joel
