Which part of the nix language looks like Perl?

I actually find the language simple and easy to learn: It's just untyped lambda calculus with dicts and lists.

(I, too, would like static types though.)

I'm not them, but TIMTOWTDI is a bad thing, and Nix suffers from it. That's the main Perl-ism I can think of.
