Rust's major goals this year are around learnability and productivity; maybe come check it out again someday :)

Could you point to any materials (e.g. blog post, roadmap document...) that deal with this? Thanks.

https://blog.rust-lang.org/2017/07/05/Rust-Roadmap-Update.ht... is our "the year is half over" update, and has a link to the overall goals right at the top.

Awesome, thanks!
Inferred lifetimes? A man can hope :).
Inferring lifetimes from the implementation of a function won't happen for the same reason that inferring types won't happen: it is really nice for the signature of a function to not automatically be changed if the body is changed, instead programmers should be told when they might be breaking their users.
However, the compiler could (and did, I believe) run inference and suggest a fix that the programmer can explicitly include.

If it were always possible to infer all lifetimes, we'd do it. Unfortunately that's not the case.
There are a number of RFCs in the pipeline to help with lifetimes, including more elision. In no particular order:
