gollark: It has 250 dependencies.
gollark: It's not as if binary size is a massive issue nowadays. Except on embedded.
gollark: Anyway, inoteaur-nim™ is only 2.4MB, versus about 80MB for minoteaur-rs™ (both debug builds).
gollark: To really shrink your C binary try osmarkslibc™, coming soon.
gollark: Large binaries probably yes. Rust also does that. Nim doesn't somehow. I don't know why or particularly care.
