I agree that Rust appears to be significantly harder to write code in. I do not 
know why GUI libraries appear to be a big problem for Rust.

But consider also that functional programming has its problems as well, both in 
terms of expressivity and performance.

D supports FP as a useful paradigm, not as a religion. It allows one to easily 
mix&match FP with imperative code.

I figure we can do the same for ownership/borrowing, that's why it has a 
separate function attribute (@live) for it.
