Keywords.

Not yet defined.

Not yet defined.

For the moment, the iostream class definition has not yet been
extended to take bool into account.  I suspect that this will happen;
what will be defined, however, I have no idea.  (Note that the literal
strings `true' and `false' are not really very good choices.  At
least, not where I live.)
