Folks that either gave up on #Nix because of the Nix language or use it but dislike the language, what are your biggest issues with it?

I've heard people saying that the language is "bad" multiple times, but often it's left at that, without raising specific points.

Here's the few arguments that I can remember:
* It should just be JSON, TOML or YAML - I disagree, because static documents are not always enough. The ecosystem would inevitably adopt something that generates these documents e.g. via text-templating languages, and that is considerably worse IMO (see: the horror that is Helm).
* Dynamic typing - I agree to some degree, optional strong typing would be great.
* Lisp as used in e.g. Guix is better - this is completely subjective, but as a person who has never touched a Lisp, the Nix language was clearer from the very start compared to Guile. I can't tell syntax from code from data, and that (homoiconicity) seems to be a feature of Lisp in general. I guess I'm just not used to it.

#nixos 

 I never gave up on #nix, so I might not be qualified to answer this. But I found the language excellent. It's a special purpose language, and it does what it is supposed to be doing very well. I saw people trying to compare it with python and such which, IMO it's a poor comparison. It's just lambda calculus, and the way it handles the paths and derivation is brilliant. I think people tend to complain before gaining a full understanding of the language. 

I consider myself a Lisper, but I have to say, Nix is better suited for this than scheme.
