LLVM seems to be a good backend for getting more embedde support in the future as well.&lt;p&gt;Rust for me has almost everything I expect from a &amp;quot;better C++&amp;quot;, the Cargo project management is stellar, rustup is great for staying up to date, integrated testing and benchmarking is amazing. I just find there&amp;#x27;s still a lack of crates which should solve itself over time and a bit of a lack of good documentation (outside of the basic Rust language resources most crates are very hard to understand looking at docs.rs, which is especially sad given how well integrated documentation is).</text><parent_chain><item><author>ilovecaching</author><text>I was sad that D never took off.

Things might have played out much differently had they addressed these issues early on.&lt;p&gt;* aside from inertia, but older languages also had inertia once.</text><parent_chain><item><author>ilovecaching</author><text>I was sad that D never took off.
