I would like to second this :) it just looks good!

Do you think it's worthwhile to add `not-empty?' in the core?
It just feels more natural to go:
(when (not-empty? (filter even? [1 2]))
...)

There is something that confuses me:
user= (cycle [])
()
user= (= (cycle []) ())
true
user= (= (cycle []) nil)
true
user= (= () nil)
false
Thanks for answering, Frantisek

What about 'conj'? Documentation says:
(conj nil item) returns (item).
Currently:
user= (conj nil 1)
(1)
user= (conj () 1)
(1)
Idiom conj nil is used in 'reverse': (reduce conj nil coll)
Currently:
user= (reverse [1 2])
(2 1)
user= (reverse [1])
(1)
user= (reverse [])
nil
It looks that now all
Or maybe more general question: Is there any function in Clojure which
when returning empty sequence, returns nil instead of () ???
user= (butlast [1 2 3])
(1 2)
user= (butlast [1])
nil
user= (butlast [])
nil
Thanks, Frantisek

Is there something wrong with that? It looks right and like it

How should I say it... It just didn't look symmetrical to me.
So, basically, there is a difference between functions returning
sequences - depending on if they are lazy or eager. Hmm...
user= (reverse [])
nil
user= (if (reverse []) true false)
false
user= (if (seq (reverse [])) true false)

At this point test-clojure doesn't generate any new failures or errors
(except the old 'mod' function failures). Coverage is still relatively
small, but (cycle []) bug and case of (reverse []) were caught with
its help when rewriting tests :-)
Thanks for all the fixes!

Please do not rush to this version unless you are a library/tool

Move only when the libs/tools you depend upon have been ported.
Thanks to all for your feedback and input!

That was fast! ;-)
Rich, I am porting test_clojure and old 'cycle' worked as:
(cycle []) = nil
Currently:
(cycle []) = java.lang.StackOverflowError
