What I would like to see is something where people could submit a small working program in one language and a Rust expert would make a program that does the same thing in idiomatic Rust. This doesn't need to be anything too complex. A wiki would be fine, the work would be in having volunteers to make the demos. If you don't know the idioms you end up doing a sort of transliteration of the source language where the concepts may work against the nature of Rust. A developer can spend a long time barking up the wrong tree with few indicators as to which is the right tree. As an example of what I mean. Here is a program that I wrote in JavaScript specifically because I could not find a way to write it in Rust that felt like I was doing it the right way. https://codepen.io/Lerc/pen/yQxmob?editors=0010 https://codepen.io/Lerc/pen/yQxmob?editors=0010 I could come up with Rust versions that were basically emulating pointers with array indexes(and a mess when something is deleted), or map versions that incurred lots of run-time lookup. The crux of the problem, I think is either how to do a mutable graph of mutable nodes, or how to do map on a immutable graph of immutable nodes to a new immutable graph of immutable nodes in the next state along. I'm sure others have this issue of "I know how to do it in X, doing it that way in Rust is a mess, what's the right way?"
