title: Is there any way to list the functions and data structures available from the native interface in Raku?
body: <p>Mainly with the objective of creating sensible examples, I'd like to know which data structures and functions are available for use in Raku's <code>native</code> interface, as in</p>
  <pre><code>class a-class is repr('CStruct') { has int $.whatever; }
  class another-class is repr('CPPStruct') { has int $.whateverelse; }
  sub a_native_function( another-class $object ) is native {*};
  </code></pre>
  <p>Is there some way of listing them? I'd like specially to obtain examples of C++ function and data structures, so that I don't have to create and compile an external library to create an example.</p>
