I was messing around last night and added a small feature to my local
copy of gnus. Cool. I reckon it'd be useful in general, so I was going
to post it to ding. Cool.
However
Looking back at the code, I realised I used cl's find-if (I know
somewhat more common lisp than elisp). And gnus doesn't (require
'cl). So the code I'm thinking about does the following:
(let ((blah
(find-if (lambda (elem)
(whopping-great-predicatey-thing))
some-list)))
(if blah
(something using blah)
(something else)))
Can anyone suggest a vaguely idiomatic way to do this using the built-in
constructs of elisp? This is a genuine question, by the way. I'm sure
I'm being thick not spotting a neat way to write this.
