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: function_signature.rb
    path of file: ./repos/puppet/lib/puppet/pal
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Puppet
module Pal
  # A FunctionSignature is returned from `function_signature`. Its purpose is to answer questions about the function's parameters
  # and if it can be called with a set of parameters.
  #
  # It is also possible to get an array of puppet Callable data type where each callable describes one possible way
  # the function can be called.
  #
  # @api public
  #
 
    
    def callable_with?(args, callable = nil)
      signatures = @func.dispatcher.to_type
      callables = signatures.is_a?(Puppet::Pops::Types::PVariantType) ? signatures.types : [signatures]

      return true if callables.any? { |t| t.callable_with?(args) }
      return false unless block_given?

      args_type = Puppet::Pops::Types::TypeCalculator.singleton.infer_set(callable.nil? ? args : args + [callable])
      error_message = Puppet::Pops::Types::TypeMismatchDescriber.describe_signatures(@func.name, @func.signatures, args_type)
      yield error_message
      false
