      <p>Kawa provides various ways to define, create, and access Java objects.
Here are the currently supported features.
</p>
      <p>The Kawa module system is based on the features of the Java class system.

          <p>Returns the "this object" - the current instance of the current class.
The current implementation is incomplete, not robust, and not
well defined.  However, it will have to do for now.
Note:  "<code class="literal">this</code>" is a macro, not a variable, so you have to write
it using parentheses: ‘<code class="literal">(this)</code>’.  A planned extension will
allow an optional class specifier (needed for nested clases).
