i found this very interesting.. it is incredible after more then 10 years using Perl, discover 'new' point of view about some simple as a foreach (@array) loop.

++ to Re: Is it safe to append to the array you are iterating over and Re: Is it safe to append to the array you are iterating over (yes)
I'm happy to see that, once again,Perl is doing it correctly: it is a logical operetion append to a list while iterating over it. Other operations are confusing.
May be worth to add some words to Perldoc: "...get very confused if you add or remove elements within the loop body (unless you merely push something at the end),....".
there are no rules, there are no thumbs..
