# :title: NilClass as Emptiness/Nothingness
#
# = Description
# 
# The ideas here is to have nil acts more like
# an empty set than an error catcher.
# So you get responses like
#   
#   nil.include?(:x) # => nil
# 
# rather than 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 external libraries.
