For comparison, the last mile in C is quite straightforward. That instantly 
seduced me.

Speaking as someone who's only Rust experience is reading the manual, there 
seems to be a lot of dependence on library code that is implemented in unsafe Rust.

Not that this is necessarily a bad thing, as I also promote the safe/unsafe code 
dichotomy.

D needs to make @safe the default, though.
