You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: forward_decl.rb
    path of file: ./repos/rubex/lib/rubex/ast/statement
    
    the code of the file until where you have to start completion: module Rubex
  module AST
    module Statement
      class ForwardDecl 
    
        def initialize(kind, name, location)
          super(location)
          @name = name
          if /struct/.match kind
            @kind = :struct
          elsif /union/.match kind
            @kind = :union
          end
