Pure Systems is a blog at pure-systems.org written by a long-time Haskell user (10–13 years) who is currently exploring whether Zig can replace Haskell for systems work. The recurring theme is using Haskell-shaped concepts (monads, typeclasses, correct-by-construction) as a lens on languages that are nominally not functional.
Recurring framing
The author evaluates languages on three axes (introduced in zig-functional-programmers):
- Domain expressiveness — how much "noise" is needed for the program to function.
- Programmability of the type system — how well you can build correct-by-construction systems.
- mean-free-path-language — lines of code before a surprise.
