Well, there are few features I wish were in the list, this is why I didn't vote.
Compared to the other languages I looked at, the way you create packages in Perl, seemed the easiest to understand. This of course could be because I didnt seriously study the other languages ways or models, but still, it nice how it is done in Perl.
- The return context (mainly 2 scalar or list)
I like the idea that variables more or less are one of two things, a single atomic value or a list of values ().
- the <> angle brackets operator
Perl makes manipulating files a lot less intimidating, you can add, to this the test operators and how you can tie files to array, all very nice.
