 When a generic function is referenced, its type is instantiated based on the

-above on `[1, 2]` will instantiate type parameter `T` with `i32`, and require
-the closure parameter to have type `Fn(i32)`.

 The type parameters can also be explicitly supplied in a trailing
 [path](#paths) component after the function name. This might be necessary if
