Feature #3714

Updated by yhara (Yutaka HARA) about 12 years ago

=begin 
  
  Given an enumerator, there is no way to know what receiver, method and arguments it is based upon (although one could use Enumerator#inspect and parse it to get the method). 
 
  For sake of completeness and introspection, it could be useful to have access to them. 
 
  This patch adds Enumerator#receiver, #method and #arguments: http://github.com/marcandre/ruby/commit/fd4c17f7fd 
 
  Note that for Enumerator created with a block like Enumerator.new{|y| y << 1 << 2}, then receiver is a Enumerator::Generator, method is :each and arguments is []. This is consistent with inspect. 
 
  Thanks.
