obscure (adjective)
not known to many people:
- an obscure island in the Pacific
- an obscure 12th-century mystic
Why does its use in production matter? Perhaps the syntax itself is obscure, but we're not discussing syntax but general awareness. Anyway, the most common "real" use of brainfuck is to prove Turing completeness of other things by finding a way to compile them into brainfuck.
obscure (adjective)
not clear and difficult to understand or see:
- Official policy has changed, for reasons that remain obscure.
- His answers were obscure and confusing.
- "the syntax itself is obscure"
Needless to say: production use ≠ notability, for very good reason.
For example, Go got famous because of how much they pushed channels and launching thousands of green threads per app as the next big thing.
Over time, people kind of soured on these ideas, but Go was a great, simple language with good DX that built static executables.
As a contrast, languages like Kotlin or Swift also brought huge DX improvements to their respective audiences, but didn't really have any standout (novel or divisive) features that made people talk about them.
Odin's like that - it's basically C (or more accurately Pascal) with better generics and some gamedev related features, so it's not as painful to write as plain C.
