In tribute to one of my favourite scenes in Red Dwarf and wanting to use Rust, this is a simple Rust application that writes "I am a fish".
Lister: Whatch'ya doin'?
Rimmer: I'm studying for my engineering exam.
Lister: By writing on your body? Wouldn't that be cheating?
Rimmer: It's not cheating, it's simply an aid to memory.
Lister: I know! Why don't you hand your body in and let them mark that?
Rimmer: You wouldn't understand, Lister, what it's like... (insert Rimmer-rant here, where he complains about how nothing's fair)
Lister: What's the point, though? You're just gonna go in there and flunk again.
Rimmer: For your information Lister, I only failed last time by the narrowest of narrow margins.
Lister: Narrowest of narrow margins?! You walked in, wrote "I am a fish" 400 times, did a funny little dance and fainted!
Rimmer: I did not.
Lister: Yes you did. Petersen told me.
Rimmer: (mimics Lister) Petersen told me. (normally) If you must know, I wrote a discourse on porous circuits that was simlpy too radical, too unconventional, too mold-breaking for the examiners to accept.
Lister: Yeah, you said you were a fish.
