Zig hits on a lot of Zen of Python.

What really sets Zig apart from the usual suspects (C, C++, Rust) is that it has first class compile-time reflection capabilities built into the language (comptime, @field, @typeInfo, etc.) rather than bolted on as macros or templates.

Funny you make that analogy. I remember back when the two contending C alternatives were Zig and Nim, with Nim being syntactically almost a Python clone.
It seems Nim has gone the way of Crystal (Ruby version of Nim) and is just kind of there but mostly forgotten and doomed to be abandoned unless it finds a niche.

I see this claim a lot, but I'm not sure. I think it's the fact that Zig is more or less still C syntax and semantics, just... fixed. The way it does comptime does seem better than how other languages do it, but I haven't actually used it, much less for long enough to judge it properly.
Comptime is a gateway to partial evaluation, precomputing tables, and data layout optimization using the same language zig that you're familiar with when you need it and just a convenient way to handle generics when you don't.
As an example from my unfinished project, I use it to select the encoding to use [1] when resolving pointers to components [2] to reduce code size [3] as much as possible while keeping a high-level interface [4] where you don't need to care about any of it, just "map" a system over every matching entry within the database and it computes the "best" traversal for a single-thread. This is something that's generally difficult to both keep simple enough to work with and for it to generate good enough code to be worth it while retaining type safety.
Comptime enables such without much cognitive overhead as you're working in the same language as before just with lazy evaluation [5] and slightly more lenient rules around memory management making it easier to focus on working towards the desired the data model.

I haven't used Nim but your comment made me remember that language, yeah it was forgotten but I am not sure if it's completely abandoned, it seems that their team has been launching new language releases on a nice cadence: https://nim-lang.org/blog.html
Lately, a lot of work has shifted to nimomy: https://news.ycombinator.com/item?id=43894666
