This is my contribution to the call for Rust blog posts.
My experience with Rust has been overwhelmingly positive, and most of the things I still want (e.g. NLL, const functions, const generic parameters, SIMD intrinsics, etc.) are already well known and being worked on, so it seems silly to repeat them. Therefore, in this post I'm just going to highlight three small-ish things that have been mildly frustrating to me over the last year, but which I haven't seen mentioned recently.
