Re: Array iterator factory

Just a minor point: using a (\@) prototype in the definition of array_iterator, as opposed to just using @_, rules out uses like array_iterator(1..10). Is there a particular benefit of using a prototype here that you are after?

If I took a list, I'd have to make and store a copy of its contents. It would be expensive, and it would not see subsequent changes to the original array. I wanted a lightweight iterator tied to a user-modifiable array. The user can create an anonymous array and slap an iterator on it, if he so desires: `array_iterator(@{[1..10]})`. That makes it obvious that this iterator can't give you the free lunch that `for (1..10)` does. Caution: Contents may have been coded under pressure.	[reply] [d/l] [select]

Don't forget the power of `&array_iterator([1..10])`. - tye	[reply] [d/l]

I'm sorry, Tye, I may be a little dopey this evening. What point are you making? Update: Ah, it's related to ihb's post. Using & to call functions bypasses prototypes. Caution: Contents may have been coded under pressure.	[reply]
