Is there a pattern they must/should follow? Using (ice-9 documentation), I've been looking at some procedure signatures. For what I can tell, they are described in the first line of `object-documentation'.
Here are some examples: (object-documentation car) => "- Scheme Procedure: car " (object-documentation cdr) => "- Scheme Procedure: cdr " (object-documentation list) => "- Scheme Procedure: list . objs" (object-documentation array-ref) => "- Scheme Procedure: array-ref v [idx0 [idx1 . idxN]]" `car' and `cdr' don't show a lambda list. `list' shows a dot, which I assume it's an indication that the following parameter is a rest. `array-ref' too has a dot, but it also has []s which IIUC represent optional arguments but are not valid lambda list constituents.
