How often do you really use Integer#times in Ruby, compared to other looping / iteration constructs? At $WORK I just checked our codebase:</div><div><br></div><div>each: 1234</div><div>map/collect: 35</div><div>times: 24</div><div>select: 19</div><div>reject: 18</div><div>inject: 9</div><div><br></div><div><div>Almost ever instance of times() is for the same basic purpose: generating a random sequence of length N. There's probably also a lot of uses of each() which should be one of the others, but I work mostly with folks with an imperative, not functional mindset.</div><div><br></div><div>Anyway, the point is, if times() is something you do a lot, just write it and get on with your life. If it matters to you a lot, make an argument for why it's generally important and submit a patch to the standard libraries.</div><div><br></div><div><br></div><div>-kevin</div></div></div></body></html>
