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: try.rb
    path of file: ./repos/dry-monads/lib/dry/monads
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Dry
  module Monads
    # Represents a value which can be either success or a failure (an exception).
    # Use it to wrap code that can raise exception
    
        def pure(value = Undefined, exceptions = DEFAULT_EXCEPTIONS, &block)
          if value.equal?(Undefined)
            Value.new(DEFAULT_EXCEPTIONS, block)
          elsif block.nil?
            Value.new(exceptions, value)
          else
            Value.new(value, block)
          end
