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: defined.rb
    path of file: ./repos/opal/lib/opal/nodes
    
    the code of the file until where you have to start completion: # frozen_string_li
    
      def compile
        case value.type
        when :self, :nil, :false, :true
          push value.type.to_s.inspect
        when :lvasgn, :ivasgn, :gvasgn, :cvasgn, :casgn, :op_asgn, :or_asgn, :and_asgn
          push "'assignment'"
        when :lvar
          push "'local-variable'"
        when :begin
          if value.children.size == 1 && value.children[0].type == :masgn
            push "'assignment'"
          else
            push "'expression'"
          end
