[MacRuby-devel] Creating ruby objects in Objective-C

[Alan Skipp]

Brilliant suggestion Eloy, much appreciated.
There's a noticeable improvement in speed using this technique. In the method which added ruby objects to an array, 77% of the time was spent on initialising the objects, that's now down to 35%.
