Hi,

A Ruby integer is always an instance of the built-in classes ::Fixnum or 
::Bignum. You cannot have different integers depending on the 
surrounding module.

This is actually a good thing, because you certainly don't want such 
elementary objects to behave context-dependend. Imagine you make a 
calculation and get different results for different modules.

I would generally avoid messing with the built-in classes. Sometimes it 
does make sense to add convenience methods, but something like 
"print_times" isn't really worth it in my opinion.
