 /// This library defines individual world impacts.
 ///
 /// We call these building blocks `uses`. Each `use` is a single impact of the
 /// world. Some example uses are:
 ///
 ///  * an invocation of a top level function
 ///  * a call to the `foo()` method on an unknown class.
 ///  * an instantiation of class T
 ///
 /// The different compiler stages combine these uses into `WorldImpact` objects,
 /// which are later used to construct a closed-world understanding of the
 /// program.
