- A decent lisp-aware editor (e.g. Emacs) will provide editing commands to manipulate Lisp source at a syntactic level (i.e. delete list, swap sublists, ...). It's pragmatic and it works, though it doesn't go nearly as far as real structured editing or projectional editing. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "The Java Posse" group.
