# :title: NilClass as Emptiness/Nothingness
#
# The ideas here is to have nil act more like
# an empty set than an error catcher.
# So you get responses like
#
# nil.include?(:x) # => nil
#
# instead of an error being raised.
#
# WARNING! One should be aware that in some rare cases
# incompatabilites may arise when using these methods in
# conjuction with other libraries.

#require 'facet/nilclass/length'
# Effectively, the following is what happens:
#
# class NilClass
# def to_f; 0.0; end
# def to_h; {}; end
# def size; 0; end
# def length; 0; end
# def empty?; true; end
# def [](*args); nil; end
# def include?(*args); nil; end
