I was re-reading the camel book, and I was puzzled by a sentence which says (Translated back to english from my french camel book, I hope it'll make sense) :

You can put an optional comma at the end of every list. It will make further item addition easier

@numbers = (
1,
2,
3,
);
I was wondering what does that easy mean ?

Will be item addition faster ?
Will item addition use memory more wisely ?

I've even played with timethese to see if the former was the answer but I must admit that I didn't had any result (In fact I'm almost sure that anyway I'm not testing the right way...)

So here are my questions :

What does it means ?
and
Where can I find answer to those kind of questions (except in the perl sources which are beyond my understanding at the present time (and for a long time anyway ;-) ?

I've ordered 'advanced programming'; can you Perl gurus suggest me another book or another source of information ?
