Subject: [ruby-core:72163] [Ruby trunk - Feature #11824] Add Enumerator#to_ary for added implicit behavior

Issue #11824 has been updated by Daniel P. Clark.


Other than syntactic cleanliness and possible public opinion, no I don't have a compelling reason why things would have changed.

I think what I'd really like is to not have to call `to_a` on Enumerators for anything actionable (any verbs).  I think you're right it may be a bad idea as many systems may have issue with this.

I suppose I could write my own custom class EnumArraytors ;-).  It's probably best practice to create new classes rather than change how the language itself fundamentally works.  Or I could use a Refinement to do this in my own projects whenever I want to clean the code base up.

Thanks for at least giving me an opportunity to defend the idea.  It was worth considering the options available.

----------------------------------------
Calling `Enumerator#to_a` many times can become a bit ugly in a code base.  I propose these changes to Enumerator to allow implicit Array use of all Enumerators.

~~~ruby
class Enumerator
  def to_ary
    to_a
  end

  def method_missing m, *a, &b
    return to_a.send(m, *a, &b) if Array.instance_methods.include? m
    super
  end
end
~~~
