 Inside the function signature and body, the name of the type parameter can be
 used as a type name. [Trait](#traits) bounds can be specified for type parameters
 to allow methods with that trait to be called on values of that type. This is
-specified using the `where` syntax, as in the above example.

 When a generic function is referenced, its type is instantiated based on the
 context of the reference. For example, calling the `iter` function defined
