Unfortunately, this application, or a library it uses, is using this obsolete function, and is thereby contributing to an overall degradation of system performance.

# This is motivated/inspired by Avdi Grimm's post on Boolean Externalties
#
#   http://devblog.avdi.org/2014/09/17/boolean-externalities/
#
# In his post he asks the question: if a predicate returns false, why does it do so?
# If you chain a lot of predicates, it's hard to figure out why you get the answer you get. Consider this example:

# This implements some simple chained predicate logic to determine if the object is scary.
class SimpleBoo

#!/usr/bin/env ruby
# Goal:
# I want to overwrite an existing method on a class by using a module, 
# instead of opening up the class and overwriting the method.
# 
# Problem:
# Modules are treated kinda like a superclass. 
# This means you can't use it to override a method, 
# because it lies further away in the method call chain.
