I just use Rust for toy projects, my work is all around Java, .NET and C++, so my feedback is more from the language geek point of view that would like to see Rust gain more adoption on the kind of workflows I use those languages.

So while it may seem like bashing, it is more trying to be a positive critic of something that real matters and is a show stopper for some environments.

In any case I look forward to any improvement in build times, and an eventual story regarding binary libraries.
