params Methods

How are params methods represented in the AST?
def Method(*args as (int)):
   print args.Length

translates to
<Parameters Name="args">
 <Type xsi:type="ArrayTypeReference">
   <ElementType xsi:type="SimpleTypeReference" Name="int" />
 </Type>
</Parameters>

Looking at BooPrinterVisitor, it seems there isn't any code to output the *.
