I guess long ago I would have said the same. But even parsing CSV benefits from Ruby's object orientation. Maybe it's just familiarization but for me it feels so much more natural to use objects and classes. Maybe it's that it is so easy to write a full fledged class in Ruby that you can even have it in one line:

# class def
DBA = :name, :login, :skills

# one instance
mladen = "Mladen", "I made this up", [:oracle, :mysql]

# output
puts "#{}'s skills include #{mladen.skills.join ', '}." -> Mladen's skills include oracle, mysql.

But I get carried away. ;-)

Yes, that observation is right. OO creates at least one more dimension of complexity.

That is never a nice experience.

I think Perl's major fault is that they overdid it in some areas: including Perl code inside a regexp is just insane IMO; also, there are often so many special cases that do some magic that it is hard to read the code as a casual Perl coder. For me maintainability is important.

Yes, I have to grudgingly agree that's a big plus for Perl.

And Perl's CPAN is another excellent reason to use Perl. Sigh.
