in Rome, do as the Romans do. It is certainly possible to add such a layer. However you will quickly find that all documentation, blogs, posts on the mailing list etc all use the traditional notation. Therefore it will be more productive not to use a syntax, which seems foreign to the locals.

oes not work, since element is not bound to the structure id. An #:extra-id-name option for struct could solve this. Is there another way to provide the struct element without renaming the element function? /Jens Axel -- -- Jens Axel Søgaard -- You received this message because you
