If we were to create a Rust version of this page for Haskell, what cool programming techniques would you add to it?

I try not to and if I have to I'd use string interpolation. I'm not even sure whether you're pulling my leg right know, I literally don't remember whether they have a string append operator.

Like 99.999% of the sh I ever wrote was in Makefiles and short wrapper scripts which could just as well be aliases. No argument handling past $@, no nothing the language is just too fickle for me to bother dealing with. The likes of zsh are make-up on a pig, I think I had a quick run-in with fish but never really got the hang. Nushell is different, it's actually bold enough in its changes to get rid of all the crufty nonsense.

Sorry, I thought you meant the use of .. in Rust is odd. So I pointed out that {0..9} and{a..z}is also used at least in bash and zsh. That's at least 10s of millions of users!

I know of .. being used for appending by lua at least. So still not odd-ball I would argue, since the people who interacted with lua code in their life probably outnumber those who interacted with all functional languages combined.

Now that you mention it yes Lua is probably the one that I remember. It's an incredibly well-designed language from start to finish but also culturally an odd-ball. .. isn't even the biggest offender: Their indices start at 1. Haskell accosts you with zygohistomorphic prepromorphisms but at least [1,2,3] !! 1 is 2.
