Having this would definitely be very useful. I remember having searched for a 'count_by' method more than once in the past.

Feature #11076: Enumerable method count_by

I very often use `Hash[array.group_by{|x|x}.map{|x,y|[x,y.size]}]`.
Would be nice with to have a method called `count_by`:
~~~ruby
array = ['aa', 'aA', 'bb', 'cc']
p array.count_by(&:downcase) #=> {'aa'=>2,'bb'=>1,'cc'=>1}
~~~
