Not exactly related to syntax, but one of the issues I've found with following the tutorials is that there is only a handful working programs which actually show the feature in question in use. While I understand that (as the tutorial explicitly mentions) the tutorial is very terse and quick glance at the language features, I feel it could be improved tremendously if there was even one a few line fully compilable program exploring the features per section.
Then again I also understand that because the language changes and evolves, maintaining more code in the docs means more effort. However, this is one of the few things I've felt bugging me as an end-user. Of course I believe this can be expected to change for the better in the future as the language matures and stabilizes, but I figured I'd voice this out given this perfect opportunity. :)
That's a good idea, but it's going to require a bit of thought to implement. It might make sense to have an "advanced examples" external page for every section in the tutorial, which would sort of transform the current tutorial into an annotated table of contents. Which could be really neat! But perhaps it should wait until Rust has some analogue to play.golang.org available.
