[parenscript-devel] Loops that return a value

It seems that the looping constructs don't currently return a value. In other words, they don't return an array of the results. CoffeeScript allows for both scenarios, that is, looping for side-effects and looping that returns an array of results. I'm thinking it would be very useful to have dotimes*, dolist*, for-in*, etc. that return an array of results. Below is an example from coffeescript.org. Let me know what you think.

countdown = (num for num in [10..1])

------------------------------------

var countdown, num;

countdown = (function() { var _i, _results; _results = []; for (num = _i = 10; _i >= 1; num = --_i) { _results.push(num); } return _results; })();
