Very true. You might get into problems if you have more %'s than arguments
perhaps.

What you lose is:

        * some type checking

What you gain:

        * less code that can contain errors
        * any errors are quickly discovered
                ('reading from /proc/sys/net/blah/blah gives garbage/crashes
                  my kernel')
        * any errors are quickly diagnosed (only 1 line where they can be)

It's a bit like putting all your eggs in one basket. This makes sense if you
gave a really good basket.
