Add default predicate argument to filter, every?, take-while

Here's a patch for: some, not-any?, every?, not-every?. If this is roughly what's wanted I'll be happy to add filter, remove, take-while, drop-while.</p> <p>Note that there are a few cases of (every? identity ...) and (some identity ...) in core.clj itself; the patch removes "identity" from those.</p> <p>clj-450-add-default-pred-arg-to-core-fns-patch.txt dated Apr 26 2012 is identical to Jason Orendorff's, except it is in git format. Jason is not on the list of Clojure contributors as of today. I have sent him an email asking if he has done so, or is planning to.</p> <p>Of course I'd be happy to send in a contributor agreement. ...Is there actually any interest in taking this patch or something like it?</p> <p>I don't know if there is any interest in taking this patch. Perhaps a Clojure screener will take a look at it and comment, but I am not a screener and can't promise anything.</p> Global Rank
