Hallo, A little distraction from discussions on language development to our daily problems. We use camlp4 for code generation. However, camlp4 has a bug associated with optional parameters -it does not work for standard syntax. It works only for revised syntax. This is the reason why we have passed on to it. Basically, revised syntax is more correct and the code reads easier, it also eliminates certain drawbacks of standart syntax. One serious problem is that there are no correct editor-programs which support this syntax. If someone from distribution uses revised syntax, could you please tell what you use. There no plugins for emacs or eclipse. There is one only for vim, but it also fails to work correctly. Thanks in advance!
