- symmetric with writeRaw() etc for the output stream. These are
methods that are not required by normal users, but which provide
a finer granularity for reading.
- additional information about the current stream position when
endList fails. This may help when tracing errors.
STYLE: change return type of beginRaw()/endRaw() to bool
- was of type Ostream& for output, but return value was unused.
Having bool may be better for encapsulating logic
STYLE: remove unused Istream::readEndBegin() function
