That's what got me off Perl. I loved it and was skeptical about Python, but one time after trying it for a week or so, I wondered what it would look like to pass a dict of lists of dicts into a function, then reference items inside it. My first try worked: I made a dict, with a list inside it, and a dict inside that list, and passed it as an argument without any sigils or reference decorators or anything.

That was about the time I stopped using Perl for any new projects. I never wanted to go back.
