      <p>Kawa has some basic support for parameterized (generic) types.
The syntax:
</p>
      <pre class="screen">Type[Arg1 Arg2 ... ArgN]
</pre>
      <p>is more-or-less equivalent to Java’s:
</p>
      <pre class="screen">Type&lt;Arg1, Arg2, ..., ArgN&gt;
</pre>
      <p>This is a work-in-progress.  You can use this syntax with
fully-qualified class names, and also type aliases:
</p>
      <pre class="screen">(define v1 ::gnu.lists.FVector[gnu.math.IntNum] [4 5 6])
(define-alias fv gnu.lists.FVector)
(define v2 ::fv[integer] [5 6 7])
(define-alias fvi fv[integer])
(define v3 ::fvi [6 7 8])
</pre>
