[CLJ-1115] multi arity into http://dev.clojure.org/jira/browse/CLJ-1115 Clojure <p>Any reason why into isn't multi arity?</p> <p>(into to & froms) => (reduce into to froms)</p> <p>(into #{} <span class="error">[3 3 4]</span> <span class="error">[2 1]</span> <span class="error">["a"]</span>) looks better than (reduce into #{} [<span class="error">[3 3 4]</span> <span class="error">[2 1]</span> <span class="error">["a"]</span>])</p> CLJ-1115

Enhancement Trivial Open Unresolved Unassigned Yongqian Li Sun, 25 Nov 2012 07:50:56 -0600 Sun, 9 Dec 2012 07:39:55 -0600 0 1 <p>Seems to be a valid enhancement. I can't see any issues we'd have with it. Vetted. </p> <p>Added patch & test. This patch retains the old performance characteristics of into in the case that there is only one collection argument. For example: (into [] <span class="error">[1 2 3]</span>) . </p> <p>Since the multi-arity version will be slightly slower, I opted to provide it as a second body instead of unifying both into a single body. If someone has a problem with this, I can rewrite the patch. At least this way, into won't get slower. </p> <p>This is a good example of an idea for an enhancement I haven't approved, and thus is not yet vetted.</p> Global Rank Patch Code and Test
