Why are authors of highly performant code allergic to readability?

This is from Chumsky, an otherwise great parser combinator. The docs are missing some critical information and the fields don't have names.

@lbfalvy must be a mental thing, they think preformant code means short lines, and short lines means short variable names

Readability is lava

When performance is primary, readability is secondary

@Hazarth this isn't sacrificing readability for performance, this is sacrificing readability for character count.

Except for the constructor, nowhere is this thing used as a tuple. The fields are exclusively accessed using dot syntax.

One think fuck you 😂😂😂

because they're used to unreadable code since huge number of times, the most performant code is unavoidably the least readable
