`iterate` reducer

Enhancement Major Open Unresolved Unassigned Alan Malloy Thu, 10 May 2012 21:40:46 -0500 Fri, 12 Oct 2012 08:10:52 -0500 Release 1.5 0 2 <p>Should I have made this implement Seqable as well? It wasn't clear to me, because as far as I could see this was the only function in clojure.core.reducers that's generating a brand-new sequence rather than transforming an existing one.</p> <p>Previous version neglected to include the seed value of the iteration in the reduce.</p> <p>Currying iterate seems useless, albeit not harmful. </p> <p>While implementing repeat, I couldn't use currying. Because 1-arity is already reserved for infinite repeat (<span class="error">&#91;n x&#93;</span> and <span class="error">&#91;x&#93;</span>, not <span class="error">&#91;n x&#93;</span> and <span class="error">&#91;n&#93;</span> if currying)</p> <p>How about we just support currying for functions where last param is reducible?</p> <p>This new patch replaces the previous patch. As requested, I am splitting up the large issue <a href="http://dev.clojure.org/jira/browse/CLJ-993" title="`range` reducer">CLJ-993</a> into smaller tickets.</p> <p>Does not depend on any of my other reducer patches, but there will probably be some minor merge conflicts unless it is merged after <a href="http://dev.clojure.org/jira/browse/CLJ-1045" title="Generalize/refactor implementation of PersistentVector/coll-fold">CLJ-1045</a> and <a href="http://dev.clojure.org/jira/browse/CLJ-1046" title="Drop-while as a reducer">CLJ-1046</a>, and before <a href="http://dev.clojure.org/jira/browse/CLJ-993" title="`range` reducer">CLJ-993</a>.</p> Approval Vetted Global Rank Patch Code and Test
