 Priority:  blocker               |   Milestone:

----------------------------------+-----------------------------------------
 If a Proc is defined that uses 'enumerateObjectsUsingBlock' and that proc
 is then called on all items of an array by iterating through the array
 with 'enumerateObjectsUsingBlock', the parameters to both blocks are sent
 to the inner enumeration. Example below.

 {{{
 framework 'Foundation'

 proc = Proc.new do |arg|
   [1,2,3].enumerateObjectsUsingBlock( Proc.new { |o, i, s| puts "inner
 enumeration #{o}" } )
   puts arg.upcase
 end

 %w[a b c].enumerateObjectsUsingBlock( Proc.new do |obj, idx, stop|
   proc.call(obj)
 end
 )
 }}}

 Output:

 {{{
 inner enumeration 1
 inner enumeration 2
 inner enumeration 3
 A
 inner enumeration b
 inner enumeration c
 }}}

 Expected output:

 {{{
 inner enumeration 1
 inner enumeration 2
 inner enumeration 3
 A
 inner enumeration 1
 inner enumeration 2
 inner enumeration 3
 B
 inner enumeration 1
 inner enumeration 2
 inner enumeration 3
 C
 }}}
