  I used __call in my syslog module [1].  I got tired of 

	syslog.log('debug',"this is a test message")

which I felt redundant.  Sure, I could have just returned the function as
the module, but then I would lose syslog.open() (to set the identity of the
program and the facility to log to).

  I've also used it for two other modules where the module names are
basically the same as the function name (iconv [2], magic [3] and uuid [4]
are some other examples).  I don't use it often, but when I do, I like it.
