[ruby-core:83065] [Ruby trunk Feature#13395] Add a method to check for not nil

Issue #13395 has been updated by znz (Kazuhiro NISHIYAMA).
I think `Array#nitems` is like this. But it was removed since ruby 1.9.1.
In doc/NEWS-1.9.1:
> o Array#nitems was removed (use count {|i| !i.nil?})

Feature #13395: Add a method to check for not nil

----------------------------------------
There does not seem to be a method in Ruby to check if an object is *not* nil.
Such a method could help with readability.
Example:
> ~~~ ruby
> array = [1, 'dog', nil]
> array.count(&:not_nil?)
> ~~~
> vs
> ~~~ ruby
> array = [1, 'dog', nil]
> array.reject(&:nil?).count
> ~~~
