Subject: bug#13678: 24.2.93; pcase: mention list-like QPatterns in the doc
Date: Sun, 10 Feb 2013 18:49:33 +0100 [thread overview]
Message-ID: <87d2w8xdn6.fsf@web.de> (raw)
Hi,
due to the doc of `pcase' (similarly in the manual), this is the list of
forms that is valid as a QPattern:
,----------------------------------------------------------------------
| QPatterns can take the following forms:
| (QPAT1 . QPAT2) matches if QPAT1 matches the car and QPAT2 the cdr.
| ,UPAT matches if the UPattern UPAT matches.
| STRING matches if the object is `equal' to STRING.
| ATOM matches if the object is `eq' to ATOM.
`----------------------------------------------------------------------
I think it should also mention list-like patterns (without dot):
(QPat1 ...QPatn) matches any n-element list were each
element matches the according QPattern
Sure, `(QPAT1 . QPAT2)' also matches lists - but `(QPAT1 . QPAT2)' and
`(QPat1 ...QPatn)' are different forms (expressions) (although those
expressions could match equal values), so IMHO both should be mentioned.
Thanks,
Michael.
