Be better about recognising side-effect-free forms, byte-optimize.el.
2011-05-07 Aidan Kehoe <kehoea@parhasard.net>
* byte-optimize.el:
* byte-optimize.el (byte-optimize-form-code-walker):
Call #'byte-optimize-side-effect-free-p on the form, rather than
just checking the plist of the form's car.
* byte-optimize.el (side-effect-free-fns):
Move the CL functions into their alphabetical place in the list.
* byte-optimize.el (function):
* byte-optimize.el (byte-optimize-side-effect-free-p): New.
Function returning non-nil if a funcall has no side-effects, which
handles things like (remove* item list :key 'car) and
(remove-if-not #'integerp list).
