oop pre salt question

[ToddAndMargo via perl6-users]

Hi All,

In the following;

   class Fruit {
       has Str  $.location is rw;
       has UInt $.apples   is rw;
       has UInt $.oranges  is rw;
       has UInt $.bananas  is rw;
   }

   #  Pre-salted:
         my $FruitStand = Fruit.new( location => "Cucamonga",
                                     apples   => 400,
                                     oranges  => 200,
                                     bananas  => 50  );

Is there a way in the class declaration that I can
set the default values such that the "my" creation
of the variable already has the default values in it?

Many thanks,
-T
