By convention method names begin with lower case letter (they can begin with the upper case letter but that makes it look like a constant).

When a method name has more than one word then the usual convention is to use underscore (e.g like_this)

Method names may end with a question mark, equasl sign and sign of excalmation.

The first convention is the method which ends with question mark returns a value that answers the question posed by the method invocation.

The second convention is any method which ends with sign of excalmation must be used with caution. Often the mehods which end with excalmation mark are mutators.

According to Martin Fowler, http://martinfowler.com/bliki/ClassInstanceVariable.html, A Class Instance Variable is a class-level variable that DOES NOT get inherited in any of the subclasses like a class variable would. Class Instance Variables are commonly used to hold references to their own instances. Using a class variable in this case possibly wouldnt make sense because all the subclasses would also get a reference to an instance of their superclass. This may not be what the programmer intended. Inserting the code below allows for class instance variables.

Code
class << self; attr_accessor :instances; end
