@Allen: I guess that cloning the array into the arguments list is indeed heavier than needed. So when large arrays are used, a method that works on arrays will be better. But for small arrays of unknown size, spreading them looks like a nice syntactical help.
@Scott: those functions are indeed interesting too, but their implementation is a lot more complex AFAICS. If you need to code that natively, you'll be busy for a while. 2015-04-29 18:56 GMT+02:00 Allen Wirfs-Brock <[email protected]>: > > On Apr 29, 2015, at 9:04 AM, C.
