Relax, we're all on the same boat. To answer each question in sequence:

1. The point of that is to terminate the program if the number of 
arguments passed is not satisfactory.

2. I don't write a library function like enforce that uses exit(1) because:

2.1. I'd have to write a ton of them.

2.2. I don't want to exit(1), I want to correctly propagate an 
exception. In this particular case it would exit straight out of main so 
it's the same as exit(1) but many scripts have more than one function.

3. I don't want to sacrifice correct behavior for anything in 
particular. It is your view that the behavior you like is correct and 
the one I like is incorrect.

Not Perl for example. I don't know whether Java prints the stack by 
default or not.
