| I wound up writing

| (some (lambda (e) e) alist)
| 
| but that seems a bit strained.

  The function identity is predefined.

| I've played "guess the word" in the HyperSpec, but can't find the idiom I
| want.

  For a single list of arguments, some may or may not be misleading.

(find-if #'identity list)
(find-if-not #'null list)

  Note that the name "alist" connotes association lists, for which this
  operation makes little sense.
