Re: drop-while and (pred item) returns nil?
By the way, I cloned the Clojure repo and have adjusted the docs for
this function, but I can't figure out how to get Github to submit it
for approval, or for a pull request or whatever it is. If someone
wants to take this patch and check it in for me, that would be fine
too.

Hi Alan,
That was my point exactly - the reference to nil in the docstring for
drop-while. It's a bit confusing to me and I'd expect a boolean
reference instead.

drop-while and (pred item) returns nil?
Hi, According to drop-while doc, (pred item) will return nil. It struck me as I thought the form would only return a boolean. Is the doc correct? What would be an example? user= (doc drop-while) - clojure.core/drop-while ([pred coll]) Returns a lazy sequence of the items in coll starting from the first item for which (pred item) returns nil.
