You're right, but the problem is that you need a debugger attached to 
catch that exception, whereas asserts help you with debugging without 
any debugger. This is part of the strength of assert. Many problems will 
cause some kind of exception that's theoretically catchable in a 
debugger, but we write asserts nonetheless, right?
