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: type_ops.rb
    path of file: ./repos/rbsyn/lib/rbsyn
    
    the code of the file until where you have to start completion: module TypeOperations
  def compute_targs(trec, tmeth)
    # TODO: we use only the first definition, ignoring overloaded method definitions
    
    
  def compute_tout(trec, tmeth, targs)
    # TODO: we use only the first definition, ignoring overloaded method definitions
    type = tmeth[0]
    return RDL::Type::DynamicType.new if ENV.key? 'DISABLE_TYPES'

    tret = type.ret
    case tret
    when RDL::Type::ComputedType
      bind = Class.new.class_eval { binding }
      bind.local_variable_set(:trec, trec)
      bind.local_variable_set(:targs, targs)
      tret.compute(bind)
    when RDL::Type::VarType
      if tret.name == :self
        trec
      else
        params = RDL::Wrap.get_type_params(trec.base.to_s)[0]
        idx = params.index(tret.name)
        raise RbSynError, "unexpected" if idx.nil?
        trec.params[idx]
      end
