No,he is correct when he says XSLT. It's a pure functional language with a terrible syntax. Nix as a language is fine. There isn't actually much to it. However

No,he is correct when he says XSLT. It's a pure functional language with a terrible syntax. Nix as a language is fine. There isn't actually much to it. However the extreme approach to laziness while quite powerful also means you can't actually follow the flow of a package. It's manifests as come from programming since with stuff in packages with no reference in yours messing with your own packages internals. It is possible to tease it out and after a while you sort of know where stuff is probably coming from. But even for someone who is pretty comfortable with Haskell and other poster children for FP, nix is a challenge to reason about code locally.
