Functional Programmers need to take a look at Zig

Code nerds are fighting over whether Zig is genius or just another pain festival

TLDR: A veteran functional-programming fan says Zig may offer a better way to write fast, predictable software without relying on automatic memory cleanup. The community instantly split between cheering a return to computer basics and roasting it as needless self-inflicted pain.

A programmer with deep roots in the world of Haskell just tossed a spicy opinion grenade into the internet: functional programmers should seriously check out Zig, a newer language that promises more control, fewer hidden surprises, and less dependence on automatic cleanup systems. The pitch, in plain English, is that Zig lets you be more explicit about what the computer is doing, which the author argues can lead to faster, more predictable software. Unsurprisingly, the comments lit up fast.

The strongest reaction was a full-on culture war: "finally, someone said garbage collection isn’t magic" versus "congrats on reinventing suffering". Supporters loved the idea that modern coders have become too cushy and too detached from how computers actually work. Critics fired back that this reads like a breakup letter from someone who got too into performance spreadsheets. Several commenters were fascinated by the author’s idea of "mean-time to surprise"—basically, how long you can code before the language does something you didn’t expect—while others mocked it as a very fancy way of saying "I hate bugs."

And yes, the jokes were flying. People compared Zig evangelism to CrossFit, called manual memory handling "rawdogging the machine," and joked that functional programmers spotting a non-garbage-collected language is like "a vegan wandering into a steakhouse and loving the knives." Beneath the memes, though, the debate was real: should programming languages protect developers from the machine, or force them to understand it?

Key Points

  • The article evaluates programming languages using three criteria: expressiveness with low noise, support for correct-by-construction and type-system programming, and "mean-time to a surprise."
  • The author is exploring Zig because of its comptime feature and its potential for flexible compile-time or type-level programming.
  • The article says the author has more than 10 years of Haskell experience and considers type-system programmability a requirement in serious languages.
  • The article argues that monads are a practical abstraction for modeling imperative and logic programming rather than merely obscure mathematical constructs.
  • The article criticizes garbage-collected functional languages for performance ceilings related to heap-heavy designs and for reducing attention to machine-level behavior.
