[traes]

From Cambridge dictionary:

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.

If you quote the dictionary to win an argument, quote it in full. There are two definitions of obscure in the Cambridge dictionary. The other is:

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"

[halperter]

Pretty sure caveat intended for the former definition.
