Ouch! Yes, that's quite a bit slower, and this code is already very slow to compile. I haven't looked at the code recently, but another option that sometimes helps is to have a base class that implements the common functionality and then derive four classes from it, but minimise the amount of code in the derived classes. Thanks for the patches!
