Hi, I'm thinking about writing up a CDR on #;-style comments. Currently, if you want to comment out a form from CL code, there is no standard way of doing this. Many people use something like #+nil, or similar tricks, but this is not 100% reliable. R6RS Scheme introduced #; as a solution, and this seems to become somewhat popular in CL as well. Here is a suggested wording. ------------- snip ----------------- #; is used to comment out single expressions; the syntax is /#; expression/. This textual notation is treated as whitespace; that is, it is as if the ``#; expression'' did not appear and only a space appeared in its place. #; operates by skipping over the form. Skipping over the form is accomplished by binding *read-suppress* to true and then calling read. ------------- snip ----------------- The text is based on 2.4.8.17 of the HyperSpec. Yes, this would be a fairly short CDR document. Any comments or ideas about this? Best, Pascal -- Pascal Costanza
