* Binding all paths matching a given prefix, using the asterisk wildcard syntax
`use a::b::*;`
* Simultaneously binding a list of paths differing only in their final element
and their immediate parent module, using the `mod` keyword, such as
`use a::b::{mod, c, d};`
and their immediate parent module, using the `self` keyword, such as
`use a::b::{self, c, d};`
An example of `use` declarations:
```
use std::iter::range_step;
use std::option::Option::{Some, None};
use std::collections::hash_map::{mod, HashMap};
use std::collections::hash_map::{self, HashMap};
fn foo<T>(_: T){}
fn bar(map1: HashMap<String, usize>, map2: hash_map::HashMap<String, usize>){}
