While there is currently no explicit varargs syntax, you could use the invoke()
meta-method to create the effect of variable argument lists for a method.  For
example:

  // invoke() is called whenever an undefined method is invoked
  invoke( String name, Object [] args ) {
      if ( name.equals("foo") )
          return fooVarargs( args );
  }

  // The variable argument version of the method takes Object []
  fooVarargs( Object [] args ) { print( args ); }

  // Invoke foo() with arbitrary number or type of arguments
  foo( 1 );
  foo( 1, 2 );
  foo( 1, 2, 3 );
  // etc.
