Subject: [ruby-core:72161] [Ruby trunk - Feature #11824] Add Enumerator#to_ary for added implicit behavior

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


According to Matz about 6 years ago this didn't seem the right thing to do.

Perhaps things have changed since Ruby 1.9.2 on this issue?

Feature #11824: Add Enumerator#to_ary for added implicit behavior

----------------------------------------
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
~~~
