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).
