Sometimes the Rust approach is simply different. For instance, 
Rust disables global variables by default; (#[feature(globs)];) 
is needed to enable them, and all accesses must be declared 
unsafe. D on the other hand just makes them all thread-local, 
requiring explicit 'shared' declarations. I think the default D 
approach here may actually be safer, and is definitely more 
convenient.
