There is still time left to add this if we need it.  I had assumed
that the application would be responsible both for opening and for
closing the stream -- is there any reason to provide a way for the
parser to signal that it's not trying to read any more bytes or
characters, when the parser will try to keep reading until EOF or an
error anyway?

What does everyone else think?

Thanks, and all the best,
