I am not sure why this is "supposed to work". QDataStream serializes
data in a fashion that can be deserialized by QDataStream again.
This typically involves some metainfo in =the serialized data like
type information and length.
QDataStream is _not_ the same as "QTextStream opened in binary mode"
or such.

Do not use 'using namespace' on file scope in headers.

#include "support/strfwd.h" might do.
