Fixnum is a subclass of Integer. For performance reasons, small  
integers will be an instance of Fixnum. This is normal. (not terribly  
relevant here, but it doesn't really mater what ErrorCount is as long  
as it has a < method which will accept 0 as an argument)

In what way is it not working ? (assuming the problem is not just that  
while and end should be lowercase)
Also in ruby a leading capital letter indicates a constant, so you'll  
probably get errors about "already initialized constant Foo" with code  
like this
