Don't forget expressions and block expressions, and all of the Ruby-esque syntax sugar around them. How expressions work with functional methods.

I write a lot of chains with block expressions that almost look 1:1 with Ruby.

There's definitely some Ruby influence (closures syntax in particulary), but I think I'd argue that Rust syntax is closer to JavaScript/TypeScript than anything else.

i suspect the example was syntax like a.b().c().d(10)
