I just noticed the function I wrote was replaced with
(dolist (key keys plist) (remf plist key))
but that does not match the behavior of remove-from-plist,
CL-USER> (alexandria:remove-from-plist (list :a 1 :b 2 :a 3) :a) (:B 2) CL-USER> (alexandria:delete-from-plist (list :a 1 :b 2 :a 3) :a) (:B 2 :A 3)
It also don't check for malformed plists. The commit message says the remf version is faster, but I found it to be around four times slower for some data and insignificantly different otherwise.
pushed (once again blindly beliving the patch author).
but this time i also pushed a test at lest that tests for the removal of duplicate keys.
sorry for blindly pushing the previous change.
