Subject: bug#48261: 28.0.50; Optimize `eql' to `eq' for fixnums
Date: Fri, 7 May 2021 11:23:40 +0200 [thread overview]
Message-ID: <1611E274-F759-4BBE-B136-FB6CDFD557B5@acm.org> (raw)

Good!
+ (and (fixnump o) (<= -536870912 o 536870911)))
Maybe write (<= (- (ash 1 29)) o (1- (ash 1 29))) instead.
+ (cl-every
Are you sure this is a good idea? See comment in the beginning of bytecomp.el.
Maybe just hold your nose and keep the existing (memq nil (mapcar ...)) hack; the list is usually short.
(We really should have fast, readable, always-available standard functions or macros for 'some' and 'every' on lists.)
