I think you've answered your own question, but you might not  
understand why.  The ruby interpreter is "executing" each line within  
the class definition as it is encountered.  If there's no  
PAYMENT_TYPES when the validates_inclusion_of line is reached, it  
really doesn't matter that it *does* appear later in the class  
definition.
