A general comment that also applies to other documents: our style guide suggests using one sentence per line: https://exercism.org/docs/building/markdown/markdown#h-one-sentence-per-line

I have auto wrap on my editor, that's probably what did it. Do you know of any automated way to format markdown paragraphs perhaps a linter or formatter doesn't necessarily need to have IDE integration.

I checked to see if students know about the mut keyword. It is mentioned in the introduction of the lasagna exercise, but I think adding a hints makes sense.

I added assignment as a prerequisites for this concept and, in cars-assemble #1675 I do exactly that. Should I still include an intro here?
Based on my understanding of the state of rust syllabus & the issues around it. I decided not to rely on existing concept exercise implementations. All of my implementations are either completely independent or only build up on what I have added (& will add soon). My focus currently is to split them into much smaller chunks so later we can implement Rust specific concepts without hesitation.

We can avoid explicit return entirely.

This is inspired by the same on csharp track. Provides introduction to while loops & floating point numbers.

The author of this PR has stopped responding in the discussions planning the work on the syllabus. But there's been a lot of work put into reviews already, so I'm keeping it open in case it can be salvaged in a future attempt to create a good syllabus. |
