When to use Prototypes?
I think I'm about to lose my newly earned 'monk' status with this post, but here goes anyway.First, it helps for readability of larger scripts, and just by looking at my sub prototypes at the top I know what to pass it.Second, for maintainability, when I look at stuff I wrote months ago I can see exactly what I'm passing and how to reuse that sub easily.
I use prototypes for any sub I write that does not take a scalar(s) as args. I do this for 2 reasons:
Now this could also be because I write too much C, and like to see what is being passed around at a glance, personally, prototyping helps. Being able to pass an array ref (like you have to) in the same way I would (logically) pass an array (like I would want to) is also more readable for me.
