An int has no base because base is only used in string representations. Or more simply, an int of 12 in base 10 is the same as an int of 12 in base 99. It is still 12. ...
Checking if an instance's class implements an interface?
Given a class instance, is it possible to determine if it implements a particular interface? As far as I know, there isn't a built-in function to do this directly. What options do I have (if any)?
