Note Submitter: me at chrisstockton dot org ---- For anyone who reads: anonymous at world4ch dot org Please do not confuse the singleton for a global variable, they are nothing the same. The global keyword is a way to extract a variable from the global scope into your local scope. A singleton is a way to control class instantiation, independent of scope to a single instance. In addition note the importance in design patterns, the ability to interchange interfaces and abstraction to allow easy adaption to a variety of needs and specifications through a single means of access is invaluable to many large scale enterprise applications. Specially pay-for software that has many system architectures to accommodate. However, the comment makes a good point to implement as necessary, the many principles don't apply to every problem domain. Do not conform your problem to a pattern, implement a pattern to your problem.
