If the stream is a member of a constant object (of of an object  whose
const  method  is  called),  you  are  only  allowed to call the const
methods of the stream.
But that's only an example. Declaring all  methods  const  that  don't
modify  the  state  of  the  object on which thy are applied is always
worth the effort in the long run. What  do  you  lose  declaring  them
const? Nothing.
