Hi there! It is known that loop macro allows keywords as clause start designators: (loop :for i :from 1 :to 10 :collect i) So do many html generation libs, e.g. cl-who: (:a :href ...) Iterate didn't do that and it caused problems while using iterate in conjunction with other libraries such as cl-utilities which defines collecting and collect macros. I patched iterate so that it can use keywords now: (iter:iter (:for i :from 1 :to 5) (when (oddp i) (:collect i)) (:finally (print "hurray!"))) So one need no more to import any symbols from iterate (maybe except iter itself). I also added test of "iterate with keywords" to a regression test suite. you can find a patch and a new file here. http://paste.lisp.org/display/69869 Discussion (currently empty) can be found here: http://groups.google.com/group/comp.lang.lisp/browse_thread/thread/f252c7931... Would iterate developers like to incorporate the changes to the main branch? If not, would you object against creating separate iterate-keywords project on the net? best regards Denis Budyak
