9:53:57beachClasp had one too, &va_rest or something like that.

11:01:52pjbUnfortunately, why the implementation may declare additionnal keywords, the standard doesn't provide a way to know their syntax: do they take 0, 1 or more parameters? Are they changing the parameter kind, or are they just qualifying a "normal" parameter"?
11:03:04jackdanielsince they are implementation specific, then their purpose is also implementation specific, so there wouldn't be much benefit from knowing how many parameters they take programmatically (if you don't understand semantics of them)

11:03:34pjbjackdaniel: it prevents parsing lambda-lists with them conformingly.
11:04:03pjbjackdaniel: it's not a semantic question, it's a syntactic question. You want to be able to parse lambda-lists, to write macros correctly.
