Use declarations support a number of convenient shortcuts:

* Rebinding the target name as a new local name, using the syntax `use p::q::r as x;`
* Simultaneously binding a list of paths differing only in their final element,
using the glob-like brace syntax `use a::b::{c,d,e,f};`
* 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 `self` keyword, such as
`use a::b::{self, c, d};`
* Rebinding the target name as a new local name, using the syntax `use p::q::r
as x;`. This can also be used with the last two features: `use a::b::{self as
ab, c as abc}`.
* Binding all paths matching a given prefix, using the asterisk wildcard syntax
`use a::b::*;`
