For how long did you use Perl?
How frequently?
Did you pass the basic level? (I'm asking this seriously)

This answers one of my first questions.
Nested data-structures is rather basic.
I think most people get to use it on a daily basis.

Python is generally not intuitive. I once thought about learning it (and 
dropped that idea after actually looking at the language, sorry) and its 
syntax is very weird.
You must know Python in order to read it, whereas I often see C/C++ 
people "understanding" Perl very easily.

I still can't see what's "yukky" about references, isn't it the same in 
Python? Care to give us a small snippet?

As I just wrote: a few times a day, every day.

Why do you make it sound so complicated?
The thing is that it's so basic. We don't bite the bullet... (I 
personally even enjoy it, but that's me).
Generally, an object is a blessed data-structure, so there's virtually 
no difference (ok, I know there is, but I'm just trying to simplify things).
